CVE-2026-11565: CWE-862 Missing Authorization in Advanced File Manager
The Advanced File Manager WordPress plugin before 5.4.13 does not perform capability checks in several of its file management AJAX actions, allowing users with any role to which an administrator has granted file-manager access (as low as Subscriber) to read arbitrary files on the server — including sensitive configuration files — and to overwrite existing non-PHP files, which can be leveraged to compromise administrator accounts and the whole site.
AI Analysis
Technical Summary
CVE-2026-11565 is a missing authorization vulnerability (CWE-862) in the Advanced File Manager WordPress plugin prior to version 5.4.13. The plugin fails to perform proper capability checks in several file management AJAX actions. As a result, users with any role granted file-manager access, including low-privilege roles like Subscriber, can read arbitrary server files, including sensitive configuration files, and overwrite existing non-PHP files.

Potential Impact
Users with minimal privileges can access and read sensitive files on the server and overwrite non-PHP files, potentially leading to site compromise and administrator account takeover.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict file-manager access to trusted users only and monitor for suspicious activity related to file management actions.
