Vulnerability AssessmentAI

Exploitation	Exploitation requires a valid WordPress account at subscriber level or higher - the lowest default role, typically obtainable via open user registration on public-facing sites. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The NVD-assigned CVSS vector (AV:N/AC:L/PR:N/UI:N) conflicts directly with the vulnerability description, which requires an authenticated user at minimum subscriber level - the PR:N assignment appears to be an error that overstates the unauthenticated attack surface and should be verified against the vendor patch notes. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An attacker registers a free subscriber account on a target WordPress site running the vulnerable File Manager plugin - or uses previously obtained low-privilege credentials - then directly invokes the unprotected connector endpoint, which returns directory listings of the entire WordPress installation root without any authorization check. The attacker enumerates directories and downloads accessible archives or documents, potentially recovering database passwords from wp-config.php backups, private uploads, or sensitive documents stored within the WordPress tree. …
Remediation	Update the File Manager WordPress plugin to version 6.9.1 or later, which introduces proper capability checks on the affected connector endpoint; this is the vendor-released patch confirmed by WPScan at https://wpscan.com/vulnerability/d17f3de9-b0f9-4bbd-8a57-18cda9d43d79/ and by ENISA EUVD-2026-55039. … Detailed patch versions, workarounds, and compensating controls in full report.
