authlib — Vulnerabilities & Security Advisories 19

Authlib is an open-source OAuth and OpenID Connect framework primarily used for implementing authentication and authorization in applications. Historically, it has been susceptible to multiple remote code execution (RCE) vulnerabilities, cross-site scripting (XSS), and privilege escalation flaws, often stemming from improper input validation and insecure default configurations. The framework's 11 recorded CVEs highlight recurring issues in parameter handling and session management. While no major public security incidents have been documented, the consistent discovery of vulnerabilities suggests developers should implement strict input sanitization and maintain current library versions to mitigate potential exploitation risks.
