What is CVE-2026-41195?
CVE-2026-41195 is a medium-severity server-side request forgery vulnerability in mosparo, published on 12 May 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
Weakness: CWE-918
