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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-200"],"references":["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#L1635","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#L217","https://plugins.trac.wordpress.org/browser/pcloud-wp-backup/tags/2.0.2/pcloud-wp-backup.php#L572"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:45:36.895656543+00:00"},"epss":{"cve":"CVE-2026-14503","score":0.00506,"percentile":0.4323,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
