CakePHP vulnerable to Denial of Service attack through XML payloads

GHSA-q79m-c546-2g63

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (cakephp/cakephp 3.0.6, 2.6.6, 2.5.90, 2.4.99, 2.3.99, 2.2.99, 2.1.99, 2.0.99), 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.

RequestHandlerComponent had a vulnerability that would allow well crafted requests to create a denial of service attack. RequestHandlerComponent leverages Xml::build() which allows reading local files. We recommend that all applications using RequestHandlerComponent upgrade, or disable parsing XML payloads.

# Patch Next advisory brief: GHSA-q79m-c546-2g63

Advisory: CakePHP vulnerable to Denial of Service attack through XML payloads
IDs: GHSA-q79m-c546-2g63
Record: https://patchnext.com/advisories/ghsa-q79m-c546-2g63 (revision 1, source checked 26 Oct 2026, 13:56 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: cakephp/cakephp 3.0.6, 2.6.6, 2.5.90, 2.4.99, 2.3.99, 2.2.99, 2.1.99, 2.0.99. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist cakephp/cakephp: affected >= 3.0.0, < 3.0.6; >= 2.0.0, < 2.0.99; >= 2.1.0, < 2.1.99; >= 2.2.0, < 2.2.99; >= 2.3.0, < 2.3.99; >= 2.4.0, < 2.4.99; >= 2.5.0, < 2.5.90; >= 2.6.0, < 2.6.6; fixed in 3.0.6, 2.0.99, 2.4.99, 2.5.90, 2.2.99, 2.1.99, 2.3.99, 2.6.6

## Suggested inspection (read-only)
- Packagist cakephp/cakephp: 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 cakephp/cakephp.
- 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.
