Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The Media Library Assistant plugin for WordPress is vulnerable to local file inclusion and remote code execution in versions up to and including 3.09. The issue stems from insufficient validation of file paths supplied to the mla_stream_file parameter in the includes/mla-stream-image.php file, where images are processed using Imagick, enabling attackers to reference arbitrary resources.
Unauthenticated attackers can exploit the flaw by supplying files via FTP, resulting in directory listings, local file inclusion, and remote code execution with full confidentiality, integrity, and availability impact as reflected in the CVSS 9.8 score.
Public references including a Wordfence advisory and the plugin's changeset on WordPress Trac document the availability of a patched version that addresses the path-handling weakness, while proof-of-concept material has been published on GitHub and Packet Storm. The associated EPSS score remains elevated near its recorded peak of 0.9283.
