CVE-2026-94132

CriticalCVSS 9.5
Published: Translated: NVD NIST

Summary

The Joomla AcyMailing Enterprise extension in versions below 11.1.0 contains a remote code execution vulnerability in the mailbox action feature. MIME parts of incoming emails were saved to media/com_acym/upload/ with no extension check, so anyone who could email the monitored mailbox could write a PHP file into the web root.

Risk Assessment

An attacker able to send email to the monitored mailbox can write a malicious PHP file and execute arbitrary code on the server. The risk is critical as it leads to full site compromise.

Recommendation

Update the AcyMailing Enterprise extension to version 11.1.0 or later. Until patched, consider restricting access to the mailbox feature.
