CVE-2026-89316 Details

ANALYZED

This CVE record has been analyzed and enriched by NVDAPI.com as an independent party.

Description

`LoadPublicKey` resolved an EC key's curve with an unchecked type assertion, `algToOptsMap[alg].(*ECDSAOptions)`. A JWK declaring `"kty":"EC"` together with a non-EC `"alg"` — which RFC 7517 §4.4 permits — reaches that assertion and **panics**.

Remediation

  • Upgrade: 1.0.0-rc4moderate effort
  • Workaround:low effort

    Do not pass externally supplied JWK documents directly to LoadPublicKey or LoadPrivateKey. Use NewVerificationKey instead, which correctly gates the EC algorithms, or validate that kty and alg agree before loading — an EC key must carry ES256, ES384, or ES512.
