DebugKit provides a debugging toolbar for CakePHP applications. Prior to 4.10.3 and 5.2.4, the DebugKit MailPreview feature in src/Controller/MailPreviewController.php accepts a route-controlled previewName value in findPreview and passes the resolved class from App::className() to constructor execution without rejecting namespace separators or verifying that the class extends DebugKit\Mailer\MailPreview. An attacker able to access DebugKit while debug mode is enabled and the request hostname is local or allowlisted can select an unintended application class through the mail-preview preview route, resulting in arbitrary constructor execution and limited disclosure of application information. This issue is fixed in versions 4.10.3 and 5.2.4.
CVE-2026-54614
This medium-severity CVE scores 4.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 77% 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).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
