CVE-2026-89317
Published:October 23, 2026
Updated:October 23, 2026
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.
