CVE-2026-33407Public exploitNetwork attack vector

SSRF via inherited proxy and unvalidated search

Published Mar 24, 2026 · Updated Mar 24, 2026

Server-side request forgery in Wallos before 4.7.0 allows remote attackers to make the server contact arbitrary domains. The unauthenticated endpoints/logos/search.php route passes inherited HTTP_PROXY or HTTPS_PROXY values directly to cURL and incorporates an unvalidated search term into the outbound logo request. Proxy hijacking requires a configured attacker-controlled proxy; successful requests can disclose internal data or interrupt the service without modifying data.
