Detailsinfo

A vulnerability was found in Statamic CMS up to 5.73.21/6.18.0. It has been classified as critical. Affected is an unknown part of the component URL Validation Handler. The manipulation with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.73.22 and 6.18.1, the Glide image proxy's URL validation could be bypassed using an IP representation that wasn't normalized before the public-IP check. An unauthenticated user could cause the server to make HTTP requests to internal addresses — including loopback, private network, and cloud metadata endpoints. This affects sites that pass user-supplied URLs to Glide. Sites running PHP 8.3 or newer are not affected. This vulnerability is fixed in 5.73.22 and 6.18.1.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-45660 since 05/12/2026. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available.
