CVE-2026-75816
CRITICALUnauthenticated attackers can bypass WordPress plugin authorization checks to take over any user account via email overwrite and password reset.
The Frontend Admin WordPress plugin lacks capability checks when post IDs are non-numeric, allowing unauthenticated attackers to overwrite administrator emails and hijack accounts via native password resets. DIB organizations must patch this immediately as it enables account takeover without user interaction, violating NIST 800-171 access control requirements. This is not an RCE or zero-day, but an avoidable auth bypass with high embarrassment due to lack of ownership checks.
Shame score — Lack of basic capability checks in a widely deployed plugin allows unauthenticated account takeover, demonstrating negligent security design and avoidable exposure.
▸ RECOMMENDED ACTION Critical severity — schedule patching of the affected products.
The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to Authentication Bypass to Account Takeover in all versions up to, and including, 3.29.12. This is due to the pre_update_value function lacking any capability or ownership check, and ActionPost::conditions_logic() short-circuiting its current_user_can('edit_post') authorization gate whenever the post ID is non-numeric — such as the string user_1 — allowing unauthenticated form submissions to be routed to arbitrary user records without restriction. This makes it possible for unauthenticated attackers to overwrite any user's registered email address, including an administrator's, and then leverage WordPress's native password-reset flow to fully take over the targeted account.
