Lifecycle Timeline
3DescriptionGitHub Advisory
Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.6.2, the url parameter can be used to retrieve local system files. This issue has been patched in version 4.6.2.
Executive ViewAI
Wallos subscription tracker versions prior to 4.6.2 contain a local file disclosure vulnerability that allows attackers to access sensitive system files without authentication. Organizations using this self-hosted tool are at immediate risk of data exposure, including configuration files, credentials, and other sensitive information stored on affected servers.
Apply vendor patch. If immediate patching is not possible, implement network-level access controls to restrict Wallos instances to trusted internal networks only, disable external access to the application, and monitor for suspicious URL parameter patterns containing path traversal sequences (../, etc.) using WAF or intrusion detection systems.
