What is CVE-2026-81810?
CVE-2026-81810 is a high-severity vulnerability in Unknown All-in-One WP Migration and Backup, published on 18 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
The All-in-One WP Migration and Backup WordPress plugin before 7.111 does not perform any capability check on several of its AJAX actions, gating them only on an installation-wide secret which it discloses to any user permitted to export the site, allowing such a user to import an arbitrary site archive and gain administrator access. Exploitation requires an administrator to have granted the export capability to a role that does not hold the All-in-One WP Migration and Backup WordPress plugin before 7.111's own import capability, which is not a default configuration.
Weakness: CWE-269
