Prior to 1.9.0, the default RFC 7523 JWTBearerGrant.get_audiences() returns an empty list, causing JWTBearerGrant.verify_claims() to require only that an aud claim exists without matching the current authorization server. An attacker holding a legitimate assertion for another service can present it to a server that shares the signing key and uses the default grant, obtaining an access token across a trust boundary. Implementations that override get_audiences() with the server&#39;s valid audience identifiers are not affected. This issue is fixed in version 1.9.0.</p> <p>Authlib is a Python library which builds OAuth and OpenID Connect servers.
