CVE-2026-33407

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.
