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
