Summary

Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 5.0.0, the fix for CVE-2026-33407 (GHSA-hhjq-82f8-m6rc, "SSRF via HTTP Proxy Environment Variable") hardened endpoints/logos/search.php by disabling cURL proxying (CURLOPT_PROXY = '' + CURLOPT_NOPROXY = '*'). However, Wallos ships a second, near-identical, unauthenticated logo-image search endpoint — endpoints/payments/search.php — that was not given the same hardening. It still passes the HTTP_PROXY/HTTPS_PROXY environment variable straight into CURLOPT_PROXY. This issue has been patched in version 5.0.0.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of ellite/Wallos published their own advisory on GitHub. Reviewed sources take precedence over it.
