CVE-2026-25221 is a Cross-Site Request Forgery (CSRF) vulnerability in the OAuth 2.0 login implementation of PolarLearn versions up to 0-PRERELEASE-15. The flaw arises because the application does not implement or verify the OAuth state parameter during authentication with GitHub and Google providers. This allows attackers to trick victims into logging into the attacker’s account, causing victims’ data and academic progress to be stored under the attacker’s profile. The vulnerability leads to data loss for victims and potential information disclosure to attackers. Exploitation requires user interaction but no prior authentication. The CVSS score is low (2.3), reflecting limited impact on confidentiality and availability, but the integrity of user data is affected. No known exploits are currently reported in the wild. European organizations using PolarLearn should be aware of this risk, especially educational institutions relying on this platform for learning management.
