If you discover a security issue in the Graceful Boundaries specification or its conformance checker, please report it privately using GitHub's security advisory feature.
Do not open a public issue for security vulnerabilities.
In scope:
- Spec requirements that could lead services to disclose sensitive information (e.g., a required field that reveals internal architecture)
- Conformance checker bugs that produce misleading security assessments
- Threat model gaps in SECURITY-AUDIT.md (SC-1 through SC-9)
Out of scope:
- Design philosophy disagreements about what the spec should require
- Vulnerabilities in specific implementations of the spec (report those to the service operator)
- The reference implementation (Siteline) — report those at siteline.to
See SECURITY-AUDIT.md for the full threat model covering rate limit calibration attacks, security posture disclosure, validation oracles, content cloaking, and other considerations.
