Detailsinfo

A vulnerability classified as critical has been found in Admin and Site Enhancements Pro Plugin up to 8.9.0. Affected is the function recursive_html of the component Save Handler. The manipulation of the argument cfgroup/input with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The Admin and Site Enhancements (ASE) Pro plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 8.9.0 via the recursive_html function. This is due to the frontend save handler enforces only a publicly emitted nonce with no authentication check, CAPTCHA validation is bypassable by omitting an attacker-supplied key, and repeater row keys from cfgroup[input] are stored verbatim and later spliced into an eval() call in recursive_html without any sanitization or identifier validation. This makes it possible for unauthenticated attackers to execute code on the server. This requires the [post_cf_form] shortcode to be present on at least one publicly accessible page, as the nonce and session ID needed to reach the vulnerable save handler are emitted to unauthenticated visitors by that shortcode.

The advisory is shared for download at wordfence.com. This vulnerability is traded as CVE-2026-16610 since 07/22/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available.
