CVE-2026-81810— All-in-One WP Migration and Backup < 7.111 - Authenticated Privilege Escalation to Admin via Import Secret Key Disclosure

Quick assessment

Affected
Unknown All-in-One WP Migration and Backup
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

All-in-One WP Migration and Backup WordPress 插件在 7.111 版本之前，未对其部分 AJAX 请求进行权限（capability）检查，仅依赖一个全局安装范围的密钥来限制访问，而该密钥会对任何拥有站点导出权限的用户进行暴露，从而使这些用户能够导入任意站点归档并获取管理员权限。利用该漏洞需要管理员将导出权限授予某个角色，而该角色并不持有该插件（7.111 之前版本）自身的导入权限，这并非默认配置。

Vulnerability Title
All-in-One WP Migration and Backup < 7.111 - Authenticated Privilege Escalation to Admin via Import Secret Key Disclosure
Source: CVE Program / CVE List V5
Vulnerability 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.
