go-jose up to v4.1.5 checks no bounds on an RSA key's modulus and primes before validating them, so a crafted JWK costs cubic CPU time to parse (GHSA-mgcc-cww5-fp2q, CVE-2026-116587). Keyosk parses JWKs only from its identity provider's key set, through go-oidc, so the provider would have to serve such a key; the update closes it anyway.

Duplicate of #205, which Dependabot opened for the same bump with an identical go.mod and go.sum change; its checks are green. |
