What is CVE-2026-14503?
CVE-2026-14503 is a medium-severity missing authorization vulnerability in ploudapp pCloud WP Backup, published on 17 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The pCloud WP Backup plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.0.3 via the wp2pcl_ajax_process_request_inner. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract force generation of a full-site backup archive written to a publicly accessible directory, exposing wp-config.php database credentials, WordPress secret salts, and the complete PHP source tree. The resulting archive is deposited in the plugin's unprotected tmp/ directory at a predictable URL, making the extracted data accessible to unauthenticated visitors once the backup is triggered.
Weakness: CWE-200
