This allows unauthenticated attackers to store a serialized object in public site content before an administrator builds a package and later performs a migration or import that runs database search-and-replace. Duplicator Free bundles a Requests 1.7 POP chain that permits attacker-selected callbacks, resulting in direct operating-system command execution. Duplicator Pro bundles an IndexList destructor gadget that permits deletion of an attacker-selected existing file when its containing directory is writable by the installer PHP process; deletion of wp-config.php can expose the setup wizard and lead to site takeover and code execution if the attacker reaches it first and supplies a reachable database they control. The package must be created after the carrier is stored, and a later administrator migration action is required.","state":0,"publishedAt":"2026-10-21T01:30:35.849+00:00","modifiedAt":"2026-10-22T19:10:34.7+00:00","affected":[{"ecosystem":"Vendor product","name":"Duplicator – Backups & Migration Plugin – Cloud Backups, Scheduled Backups, & More","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"smub\",\n                    \"product\": \"Duplicator – Backups & Migration Plugin – Cloud Backups, Scheduled Backups, & More\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"1.5.17\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"},{"ecosystem":"Vendor product","name":"Duplicator Pro","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Duplicator\",\n                    \"product\": \"Duplicator Pro\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"4.6.10\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/767fb03a-58a3-464b-98b2-5378cfec09ae?source=cve","https://plugins.trac.wordpress.org/changeset/3687092/duplicator","https://duplicator.com/knowledge-base/changelog/#v5-0-0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-82814","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-82814","identifiers":["CVE-2026-82814"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
