CVE-2026-89316

CVSS 6.3 (medium) · published 2026-10-23

`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**.

Weakness: CWE-248
