Token disclosure via logs and authorization context
Published Aug 9, 2026 · Updated Aug 9, 2026
Information disclosure in Luciano Mammino oidc-authorizer 0.1, 0.2, 0.3, and 0.4.0 allows remote attackers to expose tokens via requests. Failure paths in src/handler.rs write raw Authorization headers and entire JWTs to CloudWatch Logs, while src/models.rs serializes all validated claims into context.jwtClaims for downstream integrations. Network access to a protected API can trigger logging without authentication, but recovery of credentials or identity data requires access to Lambda logs, log exports, or downstream integrations.
