The Everest Forms – Contact Form, Payment Form, Quiz, Survey & Custom Form Builder WordPress plugin versions up to 3.1.1 contain a code injection vulnerability (CWE-94) identified as CVE-2025-3422. This vulnerability arises because the plugin improperly validates input before executing shortcodes via the do_shortcode function. Authenticated attackers with Subscriber-level privileges or higher can exploit this flaw to execute arbitrary shortcodes, potentially leading to unauthorized code execution within the WordPress site context. The CVSS 3.1 base score is 5.4, reflecting a medium severity with network attack vector, low attack complexity, and requiring privileges but no user interaction.

An attacker with at least Subscriber-level access can execute arbitrary shortcodes on the affected WordPress site, which may lead to unauthorized code execution or manipulation of site content. The impact is limited to confidentiality and integrity with no direct availability impact. No known exploits have been reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict user roles to trusted individuals only and monitor for suspicious shortcode usage. Avoid granting Subscriber-level or higher privileges to untrusted users. Follow updates from the wpeverest vendor for any forthcoming patches or official mitigations.
