SSRF via dereferenced Referer URL
Published Apr 7, 2026 · Updated Apr 7, 2026
SSRF in DonationFundEditor.php in ChurchCRM before 6.5.3 allows remote attackers to trigger outbound HTTP or HTTPS requests. Backend or downstream logic dereferences an absolute URL from the Referer header, but the advisory identifies this root cause as a hypothesis rather than naming the responsible function. The advisory reports pre-auth reachability when the route is exposed, although its CVSS v4 assessment requires high privileges; exploitation exposes reachable HTTP services to attacker-directed requests.
