Craft CMS Potential Remote Code Execution via Twig SSTI
CVE-2025-57811GHSA-crcq-738g-pqvc
What to do
Vendor fix available. Upgrade each affected package to the fixed version on its release line (craftcms/cms 5.8.7, 4.16.6), redeploy, then verify what is actually installed.
This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Note that users must have administrator access to the Craft Control Panel, and allowAdminChanges must be enabled for this to work, which is against Craft CMS' recommendations for any non-dev environment. https://craftcms.com/knowledge-base/securing-craft#set-allowAdminChanges-to-false-in-production Note: This is a follow-up to GHSA-f3cw-hg6r-chfv Users should update to the patched versions (4.16.6 and 5.8.7) to mitigate the issue.

# Patch Next advisory brief: CVE-2025-57811 Advisory: Craft CMS Potential Remote Code Execution via Twig SSTI IDs: CVE-2025-57811, GHSA-crcq-738g-pqvc Record: https://patchnext.com/advisories/cve-2025-57811 (revision 1, source checked 26 Oct 2026, 14:35 UTC) Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected. Severity: Medium (CVSS 6.6) Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV. Vendor response: Vendor fix available; fixed versions by package: craftcms/cms 5.8.7, 4.16.6. A vendor fix does not mean a deployment is fixed. ## Affected components - Packagist craftcms/cms: affected >= 4.0.0-RC1, <= 4.16.5; >= 5.0.0-RC1, <= 5.8.6; fixed in 4.16.6, 5.8.7 ## Suggested inspection (read-only) - Packagist craftcms/cms: check the installed version with your package manager. ## Supported action Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version. ## Required regression checks - Run the test suite and a production build. - Exercise the features that depend on craftcms/cms. - Repeat the inspection and confirm that only fixed versions remain installed. ## Rollback considerations - Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward. ## Unresolved questions - Which deployments run an affected version? - Exploitation status can change. Check again before lowering the priority. - Mark the work resolved only after the fixed version is verified in production. ## Sources - Verified: https://github.com/advisories/GHSA-crcq-738g-pqvc (GitHub-reviewed advisory GHSA-crcq-738g-pqvc lists affected ranges: Packagist craftcms/cms >=4.0.0-RC1 =5.0.0-RC1 <=5.8.6) Commands are suggestions: review each one before running it.
