CVE-2026-14812Public exploitNetwork attack vector

Unauthenticated site takeover via hidden action dispatcher

Published Aug 6, 2026 · Updated Aug 6, 2026

Hidden functionality in Web SEO Services Premium SEO allows remote attackers to gain full site control through crafted HTTP requests. The seo-automation.php action dispatcher accepts unauthenticated Action parameters and invokes routines that create an administrator, overwrite the plugin with downloaded PHP, proxy attacker-chosen requests, or store unescaped front-end content. Network access to the WordPress site is sufficient; all observed builds create the hidden administrator, while builds in the 6.x line also expose code execution and SSRF.
