Symfony2 improper IP based access control

GHSA-hx53-jchx-cr52

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (symfony/symfony 2.1.4, 2.0.19), 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.

Damien Tournoud, from the Drupal security team, contacted us two days ago about a security issue in the Request::getClientIp() method when the trust proxy mode is enabled (Request::trustProxyData()). An application is vulnerable if it uses the client IP address as returned by the Request::getClientIp() method for sensitive decisions like IP based access control. To fix this security issue, the following changes have been made to all versions of Symfony2: A new Request::setTrustedProxies() method has been introduced and should be used intead of Request::trustProxyData() to enable the trust proxy mode. It takes an array of trusted proxy IP addresses as its argument: The Request::trustProxyData() method has been deprecated (when used, it automatically trusts the latest proxy in the chain -- which is the current remote address): We encourage all Symfony2 users to upgrade as soon as possible. It you don't want to upgrade to the latest version yet, you can also apply the following patches:…

# Patch Next advisory brief: GHSA-hx53-jchx-cr52

Advisory: Symfony2 improper IP based access control
IDs: GHSA-hx53-jchx-cr52
Record: https://patchnext.com/advisories/ghsa-hx53-jchx-cr52 (revision 1, source checked 26 Oct 2026, 14:25 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: symfony/symfony 2.1.4, 2.0.19. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist symfony/symfony: affected >= 2.0.0, < 2.0.19; >= 2.1.0, < 2.1.4; fixed in 2.0.19, 2.1.4

## Suggested inspection (read-only)
- Packagist symfony/symfony: 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 symfony/symfony.
- 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-hx53-jchx-cr52 (GitHub-reviewed advisory GHSA-hx53-jchx-cr52 lists affected ranges: Packagist symfony/symfony >=2.0.0 =2.1.0 <2.1.4)
