Acf Frontend Form Element - Broken Access Control (CVE-2026-15606)

Q: Am I affected by this vulnerability?

You are affected if your site runs Acf Frontend Form Element. An attacker needs any registered account, so open registration materially increases the risk.

Q: How do I fix it?

Update Acf Frontend Form Element to the latest available version. Where the vendor has not yet published a fix, remove or disable the plugin until they do. Until you can update, Request / payload inspection (WAF) in Hack Halt ProSecure contains this class of attack at the request layer.

Q: What can an attacker actually do?

This is a Broken Access Control flaw. An attacker who exploits it can reach actions or data that should have been restricted to someone else.

CVE-2026-15606

Vulnerability CVE-2026-15606 PLUGIN acf-frontend-form-element HIGH

The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.29.9. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level and above permissions, to reset the password of any user on the site, including administrators, leading to full account takeover and complete site compromise. Exploitation requires the attacker to hold a valid encrypted Current-User token obtained by accessing any Edit User form they are legitimately authorized to submit, which they then use as a known-plaintext base for the CBC bit-flipping forgery.

What to do about this

Patch promptly The consequence is significant even where an attacker needs a foothold first.

Fix it

Update Acf Frontend Form Element to the latest available version.

Where the vendor has not published a fix yet, disable the plugin until they do.

Cannot update today? Request / payload inspection (WAF) in Hack Halt ProSecure blocks this class of attack before WordPress processes the request.

Inspect request parameters and bodies for injection, traversal and file-inclusion payloads, and refuse the request rather than logging it.
