CVE-2026-79627 Advanced File Manager CVE debrief

Who should care

Defenders responsible for WordPress installations with the Advanced File Manager plugin should assess exposure and prioritize verification and remediation. This includes administrators, security teams, and vulnerability management teams. They should review the CVE record and source item for details on the vulnerability and assess potential impact.

Why it matters

Defenders should prioritize verifying and updating the Advanced File Manager plugin to prevent potential script execution and elevation of privileges. The scope of affected versions and potential impact require further verification.

• Potential script execution in the browser of anyone who opens a malicious file
• Possible elevation of privileges for users with file-manager access
• Required verification of affected versions and potential impact

Technical summary

The Advanced File Manager WordPress plugin before 6.0.0 does not correctly determine whether a stored file is an SVG before sanitising it, allowing users granted file-manager access by an administrator to store a file containing script that is not stripped and that runs in the browser of anyone who opens it, including an administrator. This vulnerability could lead to potential script execution and elevation of privileges. The plugin's handling of SVG files is flawed, allowing for potential security risks. Defenders should prioritize verifying and updating the plugin.

Defensive priority

Defenders should prioritize verifying and updating the Advanced File Manager plugin to version 6.0.0 or later, and restrict file-manager access to trusted users.

Recommended defensive actions

• Verify and update the Advanced File Manager plugin to version 6.0.0 or later
• Restrict file-manager access to trusted users
• Monitor for suspicious file uploads and script execution
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and source item provide details on the vulnerability, but the scope of affected versions and potential impact require further verification. The Advanced File Manager plugin does not correctly handle SVG files, allowing for potential script execution. Defenders should verify affected versions and assess potential impact. The CVE Program record and NIST NVD detail page provide additional information on the vulnerability.
