Detailsinfo

A vulnerability was found in Revolution Slider Slider Revolution Plugin up to 7.0.10 on WordPress and classified as problematic. Affected by this issue is the function create_wordpress_image_from_url of the file /wp-content/uploads/revslider/ai. The manipulation with an unknown input leads to a information disclosure vulnerability. Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality. CVE summarizes:

The Slider Revolution plugin for WordPress is vulnerable to Sensitive Information Disclosure in versions up to and including 7.0.10. This is due to three compounding design flaws: (1) the plugin leaks a valid backend AJAX nonce (revslider_actions) to all authenticated users including Subscribers via the admin_footer hook; (2) the wordpress.create.image_from_url action is explicitly allowlisted in the $user_allowed array, bypassing the administrator-only access control; (3) the create_wordpress_image_from_url() function accepts an attacker-controlled url parameter that is passed to import_media(), where path_or_url_exists() explicitly accepts local filesystem paths (file_exists() && is_readable()) with no restriction to remote HTTP/HTTPS URLs, and @copy() physically copies those files into the publicly accessible /wp-content/uploads/revslider/ai/ directory. The MIME type check trusts the attacker-supplied content_type parameter to derive the destination extension without verifying actual file content, and the source extension blacklist does not block many sensitive types (.sql, .log, .json, .bak, .xml, .csv, .conf, .yml, .yaml, .pem, .key, .crt, .txt, .db, etc.). This makes it possible for authenticated attackers with Subscriber-level access and above to read the contents of server files with non-blacklisted extensions by having them copied to a publicly accessible URL.

The weakness was disclosed by Luc Huynh. The advisory is available at wordfence.com. This vulnerability is handled as CVE-2026-7542 since 04/30/2026. The exploitation is known to be easy. The attack may be launched remotely. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1592 by the MITRE ATT&CK project.
