CVE-2026-89317
Description
gose parsed the JWS crit header into JwsHeader.Crit and then never read it. RFC 7515 §4.1.11 requires a recipient to reject a JWS whose listed critical extension parameters it does not understand. gose implements no header extensions, so every token carrying a non-empty crit should have been rejected — and none were.
