USN-8065-1: Authlib vulnerabilities

Ubuntu Security Advisories
1 week ago
Millie Solem discovered that Authlib did not properly restrict algorithm selection during JWT verification, allowing HMAC verification with asymmetric public keys when no algorithm was specified. A remote attacker could possibly use this issue to bypass signature verification and forge tokens, resulting in authentication bypass or privilege escalation. (CVE-2024-37568) Muhammad Noman Ilyas discovered that Authlib did not properly enforce critical header parameter handling during JSON Web Signature verification, leading to unknown critical parameters being incorrectly accepted. A remote attacker could possibly use this issue to bypass security policies in mixed deployments, resulting in authentication bypass, replay attacks, or privilege escalation. (CVE-2025-59420) Muhammad Noman Ilyas discovered that Authlib did not properly limit the size of JSON Web Signature or JSON Web Token header and signature segments. A remote attacker could possibly use this issue to cause excessive memory or processor consumption, leading to a denial of service. (CVE-2025-61920) Muhammad Noman Ilyas discovered that Authlib performed unbounded decompression when processing certain compressed encrypted tokens. A remote attacker could possibly use this issue to send a specially crafted token that can be expanded to a large size during decompression, causing a denial of service. (CVE-2025-62706) It was discovered that Authlib did not properly bind cached state information to the initiating user session during OAuth authentication flows. A remote attacker could possibly use this issue to perform cross- site request forgery attacks, resulting in unauthorized actions or authentication bypass. This issue only affected Ubuntu 24.04 LTS. (CVE-2025-68158)
