HIGH 8.8

DescriptionCVE.org

The WordPress Automatic Plugin plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient file type validation in the 'core.php' file in all versions up to, and including, 3.115.0. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

AnalysisAI

The WordPress Automatic Plugin (all versions up to 3.115.0) contains an arbitrary file upload vulnerability in core.php due to insufficient file type validation, allowing authenticated attackers with Author-level or higher privileges to upload malicious files and potentially achieve remote code execution. This is a high-severity vulnerability (CVSS 8.8) affecting a widely-deployed WordPress plugin; real-world exploitation requires valid WordPress credentials at Author level or above, but successful exploitation enables complete server compromise.

Technical ContextAI

The vulnerability exists in the WordPress Automatic Plugin, a content automation and scheduling plugin for WordPress (CPE: wp:automatic). The root cause is CWE-434 (Unrestricted Upload of File with Dangerous Type), stemming from inadequate file type validation in the core.php file. The plugin fails to properly validate file extensions or MIME types before accepting uploaded files, allowing an attacker to bypass file type restrictions. Unlike unauthenticated arbitrary file upload vulnerabilities, this requires valid WordPress user credentials with Author capability (post authoring/publishing permissions) or above, reducing the immediate attack surface but still representing significant risk in multi-user WordPress environments, agency/client sites, or compromised low-privilege accounts.
