CVE-2026-114618 Authlib: Default JWT bearer grant accepts assertions for the wrong audience

Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to 1.9.0, the default RFC 7523 JWTBearerGrant.getaudiences returns an empty list, causing JWTBearerGrant.verifyclaims to require only that an aud claim exists without matching the current authorization server. An...

CVE-2026-114618

The Authlib Python library (prior to version 1.9.0 ) is vulnerable due to an insecure default in the RFC 7523 JWTBearerGrant.get_audiences() method. Because this method returns an empty list by default, JWTBearerGrant.verify_claims() only requires the presence of an aud claim without verifying it...
