eZ Platform CSRF token in login form is disabled by default

GHSA-45qm-j4m9-whv9

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (ezsystems/ezplatform 2.5.4), 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.

Source description

As published by the source; long descriptions are shortened.

his security advisory fixes a potential vulnerability in the eZ Platform log in form. That form has a Cross-Site Request Forgery (CSRF) token, but the CSRF functionality is not enabled by default, meaning the token is inactive. The fix is distributed via Composer as ezsystems/ezplatform v2.5.4, and in v3.0.0 when that will be released. If you'd like to manually enable it in your configuration, this is done by editing your app/config/security.yml and setting the "csrftokengenerator" key to "security.csrf.tokenmanager", like this: NB: In eZ Platform 3.0 this file has been moved to config/packages/security.yaml

# Patch Next advisory brief: GHSA-45qm-j4m9-whv9

Advisory: eZ Platform CSRF token in login form is disabled by default
IDs: GHSA-45qm-j4m9-whv9
Record: https://patchnext.com/advisories/ghsa-45qm-j4m9-whv9 (revision 1, source checked 26 Oct 2026, 14:24 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: ezsystems/ezplatform 2.5.4. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist ezsystems/ezplatform: affected >= 2.5.0, < 2.5.4; fixed in 2.5.4

## Suggested inspection (read-only)
- Packagist ezsystems/ezplatform: 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 ezsystems/ezplatform.
- 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-45qm-j4m9-whv9 (GitHub-reviewed advisory GHSA-45qm-j4m9-whv9 lists affected ranges: Packagist ezsystems/ezplatform >=2.5.0 <2.5.4)
