Conversation
…0.3.0) This commit addresses several critical security vulnerabilities and aligns the system with 'Secure by Default' principles: - HMAC-Signed Opaque Cursors: Replaced raw document IDs in pagination with signed envelopes to prevent ID guessing and cursor tampering. - Cedar UID Escaping: Prevented Cedar code injection by robustly escaping Entity UIDs in AuthContext. - Mandatory Policy Validation: Added strict schema validation at the engine level to catch policy logic bugs at startup. - Metadata Protection: Moved the schema introspection endpoint behind authentication. - DoS Mitigations: Enforced request body limits (5MiB) and implemented safe MessagePack-to-JSON transcoding to handle poisoned binary fields. - URI Normalization: Hardened segment extraction in authorization middleware to prevent spoofing via malformed paths.
