Title
Incomplete fix for CVE-2026-33399: SSRF in Wallos
Summary
Wallos is an open-source, self-hostable personal subscription tracker. In versions 4.8.4 and prior, the incomplete SSRF fix in Wallos validates webhook URLs via gethostbyname() but passes the original hostname to cURL without CURLOPT_RESOLVE pinning on 10 of 11 outbound HTTP endpoints, leaving a DNS rebinding TOCTOU window. At time of publication, there are no publicly available patches.
