CVE-2026-105701: CWE-434 Unrestricted Upload of File with Dangerous Type in Mauro Cassani ACPT (Premium)
Description
The ACPT (Premium) plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.0.66 via the render function. This is due to missing capability check on the REST API form creation endpoint and unsandboxed Twig environment rendering email templates. This makes it possible for authenticated attackers, with subscriber-level access and above, to execute code on the server. The exploit requires the attacker to first create a form with malicious email_settings via the REST API endpoint, then trigger form submission to execute the injected Twig expressions.

Technical Analysis
CVE-2026-105701 describes a remote code execution vulnerability in the Mauro Cassani ACPT (Premium) WordPress plugin affecting all versions up to and including 2.0.66. The flaw arises from a missing capability check on the REST API endpoint used to create forms, allowing authenticated users with low privileges to inject malicious Twig expressions into email templates. These expressions are rendered in an unsandboxed Twig environment, enabling arbitrary code execution on the server when the form is submitted.
Potential Impact
An attacker with subscriber-level access or higher can exploit this vulnerability to execute arbitrary code on the server hosting the WordPress site. This can lead to full compromise of the server, including data theft, site defacement, or further pivoting within the network. The vulnerability has a high CVSS score of 8.8, reflecting its critical impact on confidentiality, integrity, and availability.
Mitigation Recommendations
No official patch or fix is currently documented. Since the vulnerability requires authenticated access, restricting user roles and permissions may reduce risk temporarily. Monitor the vendor's advisory channels for an official fix. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
