Summary
Statamic CMS: Server-Side Request Forgery via Glide
Details

Impact

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.

Patches

This has been fixed in 5.73.22 and 6.18.1

Severity
5.4 (Medium)
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N
