Rnlab Mobile Builder plugin versions through 1.4.2 contain CVE-2026-104799. A Subscriber-level account can POST to /mobile-builder/v1/wcfm-profile-settings, bypass a flawed strpos check, and overwrite wp_capabilities to gain Administrator rights. Wordfence scored the flaw 8.8 CVSS 3.1.

A high-severity vulnerability tracked as CVE-2026-104799 affects the Mobile Builder plugin for WordPress in all versions through 1.4.2.
The flaw enables authenticated privilege escalation.
The flaw enables authenticated privilege escalation. An attacker with Subscriber-level access or higher can exploit a REST endpoint at POST /mobile-builder/v1/wcfm-profile-settings to overwrite arbitrary user meta, including the wp_capabilities key, and grant themselves Administrator privileges.
From The CircuitryThe Feed — live briefs across tech, all day.See what’s happening →
The issue stems from two weaknesses in the wcfmmp_profile_settings() handler. A PHP loose-comparison check using strpos($key, 'mobile_builder') == 0 returns true for any key that does not contain the substring because strpos() returns false on no match and false == 0 evaluates to true. The permission_callback only verifies that the user exists, allowing any authenticated account to reach the update_user_meta() call with unsanitized key and data parameters.
A PHP loose-comparison check using strpos($key, 'mobile_builder') == 0 returns true for any key that does not contain the substring because strpos() returns false on no match and false == 0 evaluates to true.

How we verify →
WordPress site operators should act now. The CVE record lists every version through 1.4.2 as affected and does not name a patched release. Sites running the plugin should update as soon as a fixed version ships, or deactivate it until then. The references point to the affected code paths in the plugin's class-mobile-builder-wcfm.php file.
