CVE-2023-22481Public exploit

Credential disclosure via failed API request logging

Published Mar 6, 2023 · Updated Feb 25, 2025

Sensitive data exposure in FreshRSS 1.9.0 through 1.20.2 allows local users with log access to read API passwords and keys. In greader.php, authorizationToUser() routes failed requests to unauthorized() or badRequest(), which logs debugInfo() output containing the unredacted request body. API access must be enabled, a user must submit incorrect credentials, and log access then exposes the submitted secret without permitting data modification.
