Name of the Vulnerable Software and Affected Versions Wallos versions prior to 4.7.0

Description The software is a self-hostable personal subscription tracker. A server-side request forgery (SSRF) condition exists due to a lack of validation for the HTTP PROXY and HTTPS PROXY environment variables in the /logos/search.php endpoint. The server resolves DNS using user-supplied search terms, allowing attackers to initiate outbound requests to arbitrary domains through proxy hijacking.

Recommendations Update to version 4.7.0 or later.
