Description
This security bulletin contains information about 1 security vulnerability.
1) Resource exhaustion (CVE-ID: CVE-2025-61920)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the way the Authlib's JOSE implementation handles untrusted input. A remote non-authenticated attacker can send overly large amount of data via unbounded JWS/JWT header and signature segments to the application and consume memory and CPU resources, leading to a denial of service condition.
