fix(scripts): stop logging explorer API keys in verifyContract (EXSC-825) - #2248
fix(scripts): stop logging explorer API keys in verifyContract (EXSC-825)#22480xDEnYO wants to merge 2 commits into
Conversation
verifyContract echoed the fully-expanded forge verify-contract command three times, and --etherscan-api-key / --verifier-api-key values went to stdout with it. Deploy logs are shared in CI output, transcripts and pasted excerpts, and a leaked explorer key cannot be un-leaked, so route every echo of the command through a redactor instead.

…on-space IFS helperFunctions.sh reassigns IFS in several places. With "$*" the command is joined on the first IFS character, so a non-space IFS produces a colon-joined line that the redactor's [[:space:]] pattern never matches and the key is printed in full.

Preserve API-key argument boundaries.
At script/helperFunctions.sh:2148, redactVerifyCmd joins arguments before redaction. A whitespace- or newline-containing API key can therefore leak its remaining content into CI logs.
Iterate over "$@" and redact the value after each API-key flag. Do not consume another flag as a missing value. Print redacted arguments with printf '%q'. Add tests for both flags, empty or missing values, and whitespace-containing values.

https://linear.app/lifi-linear/issue/EXSC-825/verifycontract-logs-explorer-api-keys-into-deploy-output
Why did I implement it this way?
verifyContractechoed the fully-expandedforge verify-contractcommand three times. Once--etherscan-api-key/--verifier-api-keyare appended toVERIFY_CMD, those echoes print the live explorer API key in plaintext.This is not theoretical: the EXSC-823 ReceiverOIF rollout (one 10-network production deploy) wrote the key into its log 22 times. Deploy logs get pasted into tickets, shared in CI output and read in transcripts, and a leaked explorer key cannot be un-leaked.
Rather than dropping the log lines — they are genuinely useful when a verification fails and you want to rerun the exact command — this routes every echo of the command through a small
redactVerifyCmdhelper that masks only the value following the two key flags.All three echo sites are routed through it, including the one that is key-free today (it runs before the key is appended). That site is harmless right now, but redacting it too makes the invariant "every echo of
VERIFY_CMDis redacted" hold independently of the order in which flags get appended, so a future reordering cannot silently reintroduce the leak.Verified against real data rather than assumed:
--etherscan-api-keyand--verifier-api-keyvalues are both masked.VERIFY_OUTPUTor a request query string. Redacting the echoes therefore closes the complete path.Follow-up (not in this PR)
The key exposed by the EXSC-823 deploy reached a transcript and should be rotated.
