Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
npm-metadata suspicious-initial-version AI (npm-metadata): Package is 4327 days old with 6 versions; 0.0.0 is simply the initial release of a legitimate long-standing utility, not a throwaway malicious package. ai
typosquat typosquat.levenshtein:pg AI (typosquat): pff stands for 'PrintF Ftw' — a string formatting utility with no relation to the PostgreSQL client 'pg'. Levenshtein proximity is coincidental. ai
