CVE-2026-25221 describes a Login Cross-Site Request Forgery (CSRF) vulnerability in PolarLearn versions 0-PRERELEASE-15 and earlier, specifically impacting its OAuth 2.0 implementations for GitHub and Google logins. The vulnerability stems from the application's failure to implement and verify the state parameter during the authentication flow. This allows an attacker to pre-authenticate a session, tricking a victim into logging into the attacker's account, leading to data loss for the victim and information disclosure to the attacker. With a CVSS score of 8.1 HIGH, this vulnerability has a network attack vector, low attack complexity, and high impact on confidentiality and integrity. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
