CVE-2026-12240
HighCVSS 8.0Exploitation Probability (EPSS)
Low risk26th percentile — higher than 26% of all known CVEs
Summary
The Export User Data plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the unserialize function in all versions up to and including 2.2.6. This allows authenticated attackers with subscriber-level access or higher to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).
Risk Assessment
The risk for the organization is critical because deleting key files (e.g., wp-config.php) can lead to remote code execution. However, exploitation requires an administrator to trigger a user data export while a subscriber-level (or higher) user has stored a crafted serialized XLSXWriter object payload as their display name.
Recommendation
Immediately update the Export User Data plugin to the latest available version. If an update is not possible, temporarily disable the plugin and restrict subscriber user permissions.
Original NVD description (English source)
The Export User Data plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the unserialize function in all versions up to, and including, 2.2.6. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). Successful exploitation requires an administrator to trigger a user data export while a subscriber-level (or higher) user has stored a crafted serialized XLSXWriter object payload as their display name.
