CVE-2026-8442 Details
Description
The WP Review Slider Pro plugin for WordPress is vulnerable to Arbitrary File Deletion in versions up to and including 12.6.8. This is due to missing authorization checks on the wpfb_hide_review and wprp_save_review_admin AJAX handlers combined with insufficient path validation in the wpfb_hidereview_ajax() function, which uses strpos() to check that a stored media URL starts with the expected prefix but fails to sanitize path traversal sequences in the remaining relative path before passing it to unlink(). This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files on the affected site's server which may make remote code execution possible.
A vulnerability allowing arbitrary file deletion has been identified in the WP Review Slider Pro plugin for WordPress, affecting versions through 12.6.8. The issue arises from missing authorization checks in the AJAX handlers wpfb_hide_review and wprp_save_review_admin. Additionally, the wpfb_hidereview_ajax() function lacks proper path validation, as it only checks if a media URL starts with a specific prefix but fails to sanitize path traversal sequences before using the path to delete files. This vulnerability enables authenticated attackers with subscriber-level access or higher to delete arbitrary files from the server, potentially leading to remote code execution.
Users are advised to update the WP Review Slider Pro plugin to version 12.7.0 or a newer patched version.
