CVE-2026-27479Public exploitNetwork attack vector

Internal data disclosure via unchecked logo redirects

Published Feb 21, 2026 · Updated Feb 21, 2026

SSRF in Wallos before 4.6.1 allows remote authenticated users to read internal resources through subscription or payment logo URLs. The getLogoFromUrl() function validates only the initial hostname, then cURL follows as many as three redirects without rechecking each destination IP. Any authenticated user can redirect the fetch to internal services or cloud metadata, and the response is saved as a retrievable logo file.
