CVE-2026-15962

Fluent Forms Pro Add On Pack <= 6.2.6 - Authenticated (Subscriber+) PHP Object Injection to Arbitrary User Password Change via User Meta Field

Published Jul 26, 2026 CVSS 3.1 · 8.8 High EPSS < 1% KEV · Not listed
Description
The Fluent Forms Pro Add On Pack plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 6.2.6 via deserialization of untrusted input. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject a PHP Object. The additional presence of a POP chain allows attackers to change user passwords and potentially take over administrator accounts. Note: This can only be exploited if user update integration is enabled and a user meta field is mapped.
