Date: December 15, 2025

FreshRSS is a self-hosted RSS feed aggregator. In versions 1.23.0 through 1.27.0, using a path traversal inside the "language" user configuration parameter, it's possible to call "install.php" and perform various administrative actions as an unprivileged user. These actions include logging in as the admin, creating a new admin user, or set the database to an attacker-controlled MySQL server and abuse it to execute code in FreshRSS by setting malicious feed "curl_params" inside the "feed" table. Version 1.27.1 fixes the issue.
