CVE-2026-33407 Details
Description
Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.7.0, Wallos endpoints/logos/search.php accepts HTTP_PROXY and HTTPS_PROXY environment variables without validation, enabling SSRF via proxy hijacking. The server performs DNS resolution on user-supplied search terms, which can be controlled by attackers to trigger outbound requests to arbitrary domains. This issue has been patched in version 4.7.0.
A server-side request forgery (SSRF) vulnerability has been identified in Wallos, a personal subscription tracker, in versions prior to 4.7.0. The issue arises in the 'endpoints/logos/search.php' file, where the application accepts HTTP_PROXY and HTTPS_PROXY environment variables without proper validation. This lack of validation allows attackers to manipulate DNS resolutions and redirect outbound requests through malicious proxies, potentially accessing internal services or exfiltrating data via DNS.
Users are advised to update to Wallos version 4.7.0 or later, where this vulnerability has been patched.
