Statamic CMS: Server-Side Request Forgery via Glide

Moderate severity GitHub Reviewed Published May 11, 2026 in statamic/cms • Updated Jun 9, 2026

Package

composer statamic/cms (Composer)

Affected versions

< 5.73.22
>= 6.0.0-alpha.1, < 6.18.1

Patched versions

5.73.22
6.18.1

Description

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

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Server-Side Request Forgery (SSRF)

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. Learn more on MITRE.
