CVE-2026-6933: CWE-434 Unrestricted Upload of File with Dangerous Type in premmerce Premmerce Dev Tools
Premmerce Dev Tools plugin for WordPress versions up to and including 2.0 contains a vulnerability that allows authenticated users with Subscriber-level access or higher to execute arbitrary PHP code remotely. This occurs because the 'generatePluginHandler' function lacks authorization checks and the 'createFromStub' function unsafely injects user input into PHP files. The vulnerability enables attackers to create malicious PHP files in the plugins directory, leading to remote code execution.
AI Analysis
Technical Summary
CVE-2026-6933 is a high-severity vulnerability in the Premmerce Dev Tools WordPress plugin (up to version 2.0) where missing authorization in the 'generatePluginHandler' function allows authenticated users with low privileges to submit POST data that is unsafely processed. The 'createFromStub' function performs unsanitized string substitution of the 'premmerce_plugin_namespace' parameter directly into PHP stub files written to the wp-content/plugins/ directory. An attacker can inject a semicolon and arbitrary PHP code into this parameter, causing the generated plugin file to contain and execute the malicious code when accessed via HTTP, resulting in remote code execution.
Potential Impact
An attacker with Subscriber-level or higher access can create arbitrary PHP files on the server, leading to full remote code execution. This compromises the confidentiality, integrity, and availability of the affected WordPress site and potentially the underlying server.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to trusted users only and consider disabling or removing the Premmerce Dev Tools plugin if possible to prevent exploitation.
