Root Cause Analysis
The vulnerability stems from improper validation
of console note serialization. The ConsoleNote.fromString
method was responsible for parsing build log annotations without verifying their authenticity. The security fix introduced cryptographic signing (via SECRET.key
) to validate
console notes, indicating the original implementation lacked this critical security check. This matches the CWE-79 XSS pattern where untrusted input flows directly into web output without proper neutralization.
