Wallos Subscription Tracker Security Issues

Server-side request forgery in Wallos versions before 4.6.2 allows authenticated attackers to conduct arbitrary network requests through the notification tester functionality. An attacker with user privileges can exploit this to access internal services, retrieve sensitive data, or interact with backend systems on behalf of the server. Public exploit code exists for this vulnerability, though a patch is available in version 4.6.2.

Path traversal in Wallos subscription tracker versions prior to 4.6.2 allows unauthenticated remote attackers to read arbitrary files from the hosting system via a malicious url parameter. Public exploit code exists for this vulnerability, which has a high severity CVSS score of 7.5. The vulnerability is patched in version 4.6.2 and later.

Reflected cross-site scripting (XSS) in Wallos password reset functionality before version 4.6.2 allows unauthenticated attackers to inject malicious scripts by manipulating token and email parameters that are output without sanitization. Public exploit code exists for this vulnerability, affecting self-hosted instances of Wallos. A patch is available in version 4.6.2 and later.

Wallos prior to version 4.6.2 contains an authorization bypass allowing authenticated users to delete avatar files belonging to other users due to missing ownership verification on the avatar deletion endpoint. An attacker with valid credentials can enumerate or guess other users' avatar filenames to remove their files. Public exploit code exists for this vulnerability, and a patch is available in version 4.6.2 and later.

Wallos versions prior to 4.6.2 contain a server-side request forgery (SSRF) vulnerability in the webhook notification testing function that fails to restrict requests to private IP ranges, allowing authenticated attackers to read internal server responses. Public exploit code exists for this vulnerability. The vulnerability affects Wallos and has been patched in version 4.6.2.
