{"id":"CVE-2026-14503","state":"PUBLISHED","title":"pCloud WP Backup <= 2.0.3 -  Missing Authorization on the 'start_backup' AJAX Method to Authenticated (Subscriber+) Arbitrary File Read","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.","publishedAt":"2026-07-17T03:43:41.024Z","updatedAt":"2026-07-17T10:24:31.926Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["ploudapp pCloud WP Backup"],"affected":[{"vendor":"ploudapp","product":"pCloud WP Backup","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.0.3","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/0b301c6e-a3c5-4435-9bc9-fab18085fe2d?source=cve","https://plugins.trac.wordpress.org/browser/pcloud-wp-backup/tags/2.0.2/pcloud-wp-backup.php#L572","https://plugins.trac.wordpress.org/browser/pcloud-wp-backup/tags/2.0.2/pcloud-wp-backup.php#L210","https://plugins.trac.wordpress.org/browser/pcloud-wp-backup/tags/2.0.2/pcloud-wp-backup.php#L1635","https://plugins.trac.wordpress.org/browser/pcloud-wp-backup/tags/2.0.2/Pcloud/Classes/class-wp2pcloudfilebackup.php#L111","https://plugins.trac.wordpress.org/browser/pcloud-wp-backup/tags/2.0.2/pcloud-wp-backup.php#L217","https://plugins.trac.wordpress.org/changeset?reponame=&old=3597399%40pcloud-wp-backup&new=3597399%40pcloud-wp-backup"],"weaknesses":["CWE-200"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/14xxx/CVE-2026-14503.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-14503","state":"PUBLISHED","datePublished":"2026-07-17T03:43:41.024Z","dateUpdated":"2026-07-17T10:24:31.926Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-02T18:06:48.735Z"},"containers":{"cna":{"title":"pCloud WP Backup <= 2.0.3 -  Missing Authorization on the 'start_backup' AJAX Method to Authenticated (Subscriber+) Arbitrary File Read","descriptions":[{"lang":"en","value":"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.
