What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (cakephp/cakephp 5.3.1, 5.2.12), 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.

# Patch Next advisory brief: CVE-2026-23643

Advisory: CakePHP PaginatorHelper::limitControl() vulnerable to reflected cross-site-scripting
IDs: CVE-2026-23643, GHSA-qh8m-9qxx-53m5
Record: https://patchnext.com/advisories/cve-2026-23643 (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 5.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: cakephp/cakephp 5.3.1, 5.2.12. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist cakephp/cakephp: affected >= 5.2.10, < 5.2.12; >= 5.3.0, <= 5.3.0; fixed in 5.3.1, 5.2.12

## 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.

## Sources
- Verified: https://github.com/advisories/GHSA-qh8m-9qxx-53m5 (GitHub-reviewed advisory GHSA-qh8m-9qxx-53m5 lists affected ranges: Packagist cakephp/cakephp >=5.2.10 =5.3.0 <=5.3.0)
