CVE, Research URL: CVE-2024-3564
Home page URL: Security reports for Content Blocks (Custom Post Widget)
Application: Content Blocks (Custom Post Widget)
Published on: Jun 01, 2024
Research Description: The Content Blocks (Custom Post Widget) plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 3.3.0 via the plugin's 'content_block' shortcode. This makes it possible for authenticated attackers, with contributor-level access and above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.
Affected versions: max 3.3.1.
Status: vulnerable
