EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.8 under NVD CVSS v3. EPSS exploit probability: 0.6%, top 55% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A vulnerability exists in CakePHP versions 4.0.x through 4.1.3. The CsrfProtectionMiddleware component allows method override parameters to bypass CSRF checks by changing the HTTP request method to an arbitrary string that is not in the list of request methods that CakePHP checks. Additionally, the route middleware does not verify that this overriden method (which can be an arbitrary string) is actually an HTTP method.
