Name of the Vulnerable Software and Affected Versions PostX versions prior to 5.0.6

Description The Post Grid Gutenberg Blocks for News, Magazines, Blog Websites – PostX plugin for WordPress allows unauthorized modification of data. This occurs because the ultp shareCount callback() function lacks a capability check, enabling unauthenticated attackers to modify the share count post meta for any post, including those marked as private or drafts.

Recommendations Update to a version newer than 5.0.5. As a temporary workaround, consider restricting access to the ultp shareCount callback() function until the update is applied.
