What is CVE-2026-72784?
CVE-2026-72784 is a medium-severity server-side request forgery vulnerability in craftcms cms, published on 11 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Craft CMS versions >= 5.0.0-RC1 before 5.10.6 and >= 4.0.0-RC1 before 4.18.2 contain a server-side request forgery vulnerability in the GraphQL save<Volume>Asset mutation, which fetches an attacker-supplied URL server-side. The anti-SSRF validation is incomplete: validateIp() does not cover CGNAT (100.64.0.0/10) or NAT64 (64:ff9b::/96) ranges, and the only IP check runs after the request has already been issued. An attacker holding a GraphQL token scoped only to asset-creation permissions can disclose internal HTTP content from CGNAT/NAT64 targets, force outbound GET requests to internal hosts (including RFC1918, loopback, and metadata endpoints), and enumerate internal services.
Weakness: CWE-918
