The clients refuse a plaintext upload service: they ask it for an upload URL and then PUT the bundle to whatever comes back, so a plaintext hop exposes both. An operator pointing their deployment at this server therefore needs it to speak https, and until now it could only do so behind a separate terminator. SERVER_CERT_FILE and SERVER_KEY_FILE switch it to ListenAndServeTLS. They must be set together. Unset keeps the current plaintext listener, for a deployment that does terminate TLS in front of it.
…agement The debug-bundle paths that upload without a human picking a destination compiled the vendor endpoint in: the mobile clients and the desktop UI hold `https://upload.debug.netbird.io/upload-url` as a constant, the CLI defaults its flag to it, and the remote job falls back to it when nothing else is set. A self-hosted deployment therefore shipped peer logs, routes, DNS and firewall state to NetBird-run infrastructure without its operator ever configuring that, and had no way to point those paths anywhere else. #7147 and #7153 gave the remote job a per-job URL and an MDM override, but neither reaches the mobile, UI or CLI paths, and both fail open when unset. Publish the destination from the management server instead, on the channel that already carries stun/turn/signal/relay/flow/metrics: - `NetbirdConfig.debug.upload_url`, sourced from the new account setting `debug_bundle_upload_url` (REST + dashboard) and falling back to the new `DebugUpload.URL` in the management server config, which a self-hosted install can set once so a fresh account is not left on the vendor default. Both are validated as https-with-host where they are written; a change fans out to connected peers rather than waiting for the next login. - One resolver on the client, `debug.ResolveUploadURL`, used by every path: MDM override > explicitly named URL > destination published by management > the NetBird service, but only for a peer enrolled with NetBird's cloud. Anything else fails closed with ErrNoUploadDestination and the bundle stays local, which is the behaviour change: a self-hosted deployment that names no upload service no longer uploads at all. - The engine keeps the published value (`Engine.DebugUploadURL`) so the bundle paths, which run off the engine loop, do not have to read it back out of the opt-in sync-response store. - The daemon request grows `upload`, so "upload to wherever this deployment says" is expressible; an empty `uploadURL` no longer has to mean "no upload". The privilege gate is unchanged and still applies only to a URL the local caller named — a destination published by management is the operator naming their own service. - The desktop UI stops carrying a vendor URL of its own and sends the intent. Reported privately as GHSA-hf99-43rj-h577.
requirePrivilegeForUploadURL returned early on an empty URL, which was correct while an empty URL meant "do not upload": there was no destination for --upload-bundle-insecure to weaken. Now an empty URL means "use the destination the management server published", so an unprivileged local caller could send upload=true with an empty URL and uploadInsecure=true and have the root daemon PUT the bundle to that destination with TLS verification disabled. Gate the insecure flag on the empty-URL path too. A named URL keeps its existing order, so a malformed one still reports InvalidArgument rather than a privilege error.
…is configured
The previous commit made a peer with no destination — no MDM override, no URL
named by the caller, nothing published by its management server — refuse to
upload and keep the bundle local unless it was enrolled with NetBird's cloud.
That closed the reported data-boundary concern, but it broke the default for
everyone who uploads a bundle as part of their day: a self-hosted user opening
a support ticket got a refusal where the command used to work.
Product decision (NetBird's, not the reporter's): the knob to keep bundles
inside your own infrastructure is what this branch provides, and it is enough.
The default stays the service NetBird runs, self-hosted included. An admin who
needs the bundles to stay in-house configures the destination; until then the
everyday flow keeps working.
So ResolveUploadURL drops the cloud check, the sentinel error and the
managementURL argument, and never fails:
MDM > explicitly named URL > published by management > NetBird's service
Nothing observable changes for a deployment that configures nothing, which also
removes two edge cases the fail-closed default had: a peer still enrolled on the
legacy api.wiretrustee.com host would have been classified self-hosted and
refused, and an upgrade would have silently stopped uploads for self-hosted
deployments relying on them. The privilege gate is unaffected — a host other
than the default one still requires a privileged caller, so pointing the CLI
somewhere other than what management published needs root.
Engine.Start receives the login response's NetbirdConfig but only runs it through PopulateNetbirdConfig, so handleDebugUploadUpdate never saw it: the destination the management server publishes reached the engine only on the first sync afterwards. A debug bundle requested in that window resolved no published destination and fell back to the service NetBird runs, even on a deployment that had configured its own — the opposite of what configuring it is for. Seen with a remote job triggered shortly after the peer reconnected: the job succeeded against NetBird's upload service while the account setting named a different host.

Confirmed, but this was pre-existing.
With management at trace level the settings path does log
updating peers for account <id> from ...UpdateAccountPeers and then goes
silent, so the trigger fires and the work dies immediately after.
The difference is the context. account.go:463 spawns
go am.UpdateAccountPeers(ctx, ...) with the HTTP request context, which is
cancelled as soon as the handler returns; peer.go:1538 forwards it into the
controller unchanged and discards the error with _ =, which is why nothing
shows up in the logs. The DNS/policy/group path goes through
ExpandAndUpdateAffected → dispatchAffected, whose first statement is
ctx = context.WithoutCancel(ctx) — with a comment saying exactly why.
So this is pre-existing and not specific to DebugBundleUploadURL: every field
in the trigger list above is affected, including the session deadline whose own
comment in that block says the proactive-expiry warning in
client/internal/auth/sessionwatch relies on the fan-out reaching connected
peers.
Not fixing it here. It sits in the network-map controller, has nothing to do
with debug bundles, and changing it under a security PR would mix two unrelated
blast radii — a separate PR is tracked for it.
For this PR specifically the practical impact is bounded: the destination still
reaches the peer at login and on the next sync, and 803b0d6 (also from your
review) stops a partial TURN/relay update from clearing it in between. What is
lost until the fan-out is fixed is only the "takes effect within seconds"
property, not correctness.
This was referenced Sep 11, 2026
…ial config updates pushNewTURNTokens and pushNewRelayTokens send a SyncResponse whose NetbirdConfig carries only Turns and Relay. handleDebugUploadUpdate read the absent Debug as an empty destination and stored it, so every TURN credential refresh — every few minutes — silently dropped the operator's choice and the next bundle went to the service NetBird runs. That is the exact failure this branch exists to prevent. A nil DebugConfig now carries no information and is left alone. To keep an operator's clear reaching the peer, toNetbirdConfig always emits Debug on the full config it builds, empty URL included, so the peer can tell "cleared" from "not mentioned". Reported by cubic on #7514.
The URL reaches the daemon from the management server or from the caller and can carry userinfo or a token in its query. Both log lines wrote it whole, into the file that then ships inside the very bundles this uploads. Reported by CodeRabbit (CWE-532) and cubic on #7514.
DebugUpload.Validate checked url.Host, which is non-empty for an authority like ":443" even though there is no host. Management would store and publish it, and every peer would then refuse it: the client-side rule the same value meets on the CLI path already uses Hostname() for exactly this reason (profilemanager.ValidateBundleUploadURL). Reported by cubic on #7514.
…sted A request with no URL, no upload and uploadInsecure set was denied, although uploadInsecure has no effect on a local-only bundle: there is no destination to weaken, and the caller only wanted the file on disk. Pass the upload intent into the gate and apply the empty-URL branch only when the request asks to upload. Reported by cubic on #7514.
…t the requested one validateBundleUploadURL ran on the job's URL or the MDM override and then ResolveUploadURL folded in the destination published by management, which never met the same check. A malformed or plaintext published value therefore slipped through resolution and failed later inside UploadDebugBundle's requireHTTPS, surfacing as a transport error instead of a validation one. Management validates at write time, so this only bites against an older or mismatched server — but the two destinations are interchangeable and should be held to one rule. Reported by cubic on #7514.
…tBird's service The text described the empty flag as "the one the management server publishes" and stopped there, so a reader had no way to know what happens when it publishes none. Name the fallback, and scope the root requirement to a host other than NetBird's rather than to setting the flag at all. Reported by cubic on #7514.
The comment still described the fallback as reached only by a peer enrolled with NetBird's cloud, which stopped being true when the default became NetBird's service for every deployment. Left as it was, a maintainer would read it and assume self-hosted peers keep their bundles local. Reported by cubic on #7514.
…d failure WAILS-API.md listed "a deployment that publishes no upload service" among the causes of uploadFailureReason. That was true of an earlier revision; the resolver now falls back to the service NetBird runs, so the case never produces a failure. Reserve the field for a destination that rejects the upload or cannot be reached. Reported by CodeRabbit on #7514.
…ence The shape omitted anonymizeLevel, which has been on the Go struct (client/ui/services/debug.go) and set by the frontend since the strict anonymization level landed. This file is the reference for every model shape, so the omission propagates to anyone reading it instead of the generated bindings. Reported by cubic on #7514.
http.Server was built with only Addr and Handler, so every timeout was infinite. Behind a reverse proxy that is survivable because the proxy has its own; serving TLS directly, which SERVER_CERT_FILE now allows, it means a slow client can hold a connection and its goroutine indefinitely. ReadHeaderTimeout and IdleTimeout are short. ReadTimeout is 10 minutes: it has to clear a 150 MiB upload on a slow link, so it is a ceiling on a stalled connection rather than a throughput rule. WriteTimeout is deliberately left unset for the same reason. Reported by CodeRabbit (CWE-400) on #7514.
…enAPI schema The account handler rejects a non-empty value unless url.Parse yields scheme https and a host, but the schema said only "string", so a schema-driven consumer saw an unconstrained field and learned the contract from a 422. Add a pattern that allows "" for the fallback and otherwise requires https with a host. Regenerating types.gen.go produces no diff: our oapi-codegen config emits types only, so the pattern documents the contract rather than enforcing it in Go. The handler stays the thing that rejects. Reported by CodeRabbit and cubic on #7514.

Redacting the URL in the log line left the error itself untouched, and Go's
*url.Error prints the URL whole. That error does not stay local: it becomes
UploadFailureReason for the CLI and the desktop UI, and for a remote job it is
stored in the management server's job record and shown in the dashboard. A
sample from a failed job:
Client error: 'upload debug bundle: get presigned URL: Get
"https://helloworld.asda1234:2356?id=eb23d149..."'
The service URL can carry userinfo or a query token, and the presigned URL the
service hands back carries credentials in its query by design, so the second
step leaks more than the first.
UploadDebugBundle now rewrites every URL in its error down to scheme://host, on
the way out, which covers the daemon, both mobile SDKs and the job runner at
once. The original error stays reachable through Unwrap.
Reported by cubic on #7514.
…n the OpenAPI schema" This reverts commit a8817ca. The pattern was meant to mirror DebugUpload.Validate, and it does not. Go's url.Parse lowercases the scheme and accepts a bracketed IPv6 literal, so all three validators take `HTTPS://example.com` and `https://[2001:db8::1]/bundle` while the regex rejects both; in the other direction the regex accepts control characters in the path that url.Parse refuses. Measured, 3 of 4 sample values disagreed. A schema that rejects what the API accepts is worse than one that says nothing, and chasing url.Parse with a regex just creates a second rule to keep in sync. The prose description already states the requirement, and the handler stays the thing that enforces it. Reported by cubic on #7514, which offered dropping the pattern as the alternative to fixing it.

The class `[^\s"']+` ran past every delimiter that is not whitespace or a quote,
so a URL followed by `)`, `>` or a backtick took the closing character and the
words after it into the match, and everything past the small TrimRight set was
dropped from the message:
(see https://upload.example.com/x?t=1) for details
-> (see https://upload.example.com for details
Stop the match at those delimiters and leave TrimRight to sentence punctuation.

Match bracketed IPv6 hosts before redaction.
[ and ] delimit IPv6 URL hosts. For https://[2001:db8::1]/upload?X-Amz-Signature=secret, the current pattern stops after https://, leaving the credential-bearing query in durable upload errors, including UploadFailureReason and logs. Match bracketed IPv6 hosts and add a redaction test.

In `@client/internal/debug/upload.go` at line 186, Update the urlInText regular
expression to match bracketed IPv6 hosts, including their paths and query
strings, so credential-bearing URL components are fully redacted. Add a
regression test covering an HTTPS URL such as a bracketed IPv6 host with a
sensitive query parameter and verify the redaction behavior used by upload
errors and logs.

Describe your changes
The client paths that upload a debug bundle without a human picking a destination had the vendor endpoint compiled in: the mobile clients, the desktop UI, the CLI flag default and the remote job's fallback. A self-hosted operator could not redirect any of them. #7147 and #7153 gave the remote job a per-job URL and an MDM override, but neither reaches the mobile, UI or CLI paths.
Publish the destination from management instead, on the channel that already carries stun/turn/signal/relay/flow/metrics:
NetbirdConfig.debug.upload_url, sourced from a new account settingdebug_bundle_upload_url(REST + dashboard) falling back to a newDebugUpload.URLin the management server config, so a self-hosted install can set it once for every account. Both are validated as https-with-host where they are written.One resolver on the client,
debug.ResolveUploadURL, serves every path. It uses the first destination that is set: the MDM policy, then an explicitly named URL (--upload-bundle-url, or a remote job'supload_url), then what management published, and finally the upload service NetBird runs. That last step keeps the default unchanged for everyone, self-hosted included — an operator who needs the bundles inside their own infrastructure names their own upload service, and until they do the everyday "collect a bundle and send it to support" flow keeps working. Nothing observable changes for a deployment that configures nothing.Commits, bottom to top:
[upload-server]—SERVER_CERT_FILE/SERVER_KEY_FILEmake it speak https. Independent of the rest, but the clients refuse a plaintext upload service, so without it an operator cannot actually host the destination this PR tells them to configure.[management,client]— the setting, the config knob, the proto field, the resolver, and the engine holding the published value (Engine.DebugUploadURL) so the bundle paths, which run off the engine loop, do not have to read it back out of the opt-in sync-response store.[client]— the daemon request growsupload, so "upload to wherever this deployment says" is expressible and an emptyuploadURLno longer means "no upload". That made--upload-bundle-insecurewith an empty URL a way for an unprivileged local caller to have the root daemon PUT the bundle with TLS verification disabled, so the privilege gate now covers the empty-URL path too.[management,client]— the default. An earlier revision refused to upload when nothing was configured; this restores NetBird's service as the fallback (product decision).[client]—Engine.Startruns the login response's NetbirdConfig throughPopulateNetbirdConfigonly, so the published destination reached the engine only on the first sync afterwards; a bundle requested in that window fell back to NetBird's service even where the deployment had configured its own.Verified end to end against a local deployment with two peers and a TLS upload server: destination published → both peers upload there and the bundle lands intact with the object key prefixed by
sha256(managementURL); a bogus destination → the CLI and a dashboard-triggered remote job both fail with the resolution error; plaintext destination rejected by the API with 422; nothing configured → NetBird's service, unchanged.Issue ticket number and link
Reported privately as GHSA-hf99-43rj-h577 (CWE-497). The reporter asked for the fallback to NetBird's endpoint to be removed entirely; the decision was to provide the knob and keep the default, so the advisory's central request is deliberately not met. The compiled-in default it concerns is
upload-server/types/upload.go:11. Follow-up to #7147 / #7153, which covered the remote-job path only.Stack
