# CVE-2026-54242: Statamic: Server-Side Request Forgery via Glide (DNS rebinding)

- Also known as: GHSA-V5C4-WCPJ-X73M
- Severity: CVSS 4.9 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 5.73.24, 6.20.1
- Published: 2026-07-17 · Updated: 2026-07-20

## Affected

- statamic cms: fixed in 5.73.24; from 6.0.0, fixed in 6.20.1
- statamic/cms (Packagist): fixed in 5.73.24
- statamic/cms (Packagist): from 6.0.0, fixed in 6.20.1

## Description

Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.73.24 and 6.20.1, the Glide image proxy's URL validation in src/Imaging/RemoteUrlValidator.php and src/Imaging/GuzzleAdapter.php could be bypassed using DNS rebinding. The remote hostname was validated as publicly routable, but resolved again when the image was actually fetched, so an attacker controlling the hostname's DNS could rebind it to an internal address after validation and 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. This issue is fixed in versions 5.73.24 and 6.20.1.

## What to do

- Check your stack: if you ship or depend on statamic cms, statamic/cms, upgrade to a fixed version (5.73.24, 6.20.1) per the references below.
