CVE-2025-68158 describes a Cross-Site Request Forgery (CSRF) vulnerability in Authlib, a Python library for OAuth and OpenID Connect servers, affecting versions 1.6.5 and prior. The flaw stems from cache-backed state/request-token storage not being tied to the initiating user session, allowing an attacker to obtain a valid state and exploit the vulnerability. This issue carries a high CVSS score of 8.8, indicating a critical risk with potential for high impact on confidentiality, integrity, and availability, requiring user interaction but no authentication. While there is no evidence of active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB), the vulnerability has garnered significant community discussion and media coverage, including security updates from SUSE and Ubuntu.
