SSRF in Mosparo

CVE-2026-41195

mosparo is the modern solution to protect your online forms from spam. Prior to 1.4.13, the automatic rule package source URL feature allows a project member with the editor role to store an attacker-controlled URL that the server later fetches. Because the server follows http/https redirects and does not restrict private or loopback destinations, this becomes a stored SSRF primitive that can be turned into an internal HTTP probing oracle. This vulnerability is fixed in 1.4.13.
