CVE-2026-75027: CWE-862 Missing Authorization in themifyme Themify Builder
Description
The Themify Builder plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 7.8.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to modify the stored Themify Builder styling data (padding and margin properties) of arbitrary posts, including private and draft posts, by supplying an attacker-controlled post ID and JSON styling payload. The nonce required by the handler is automatically emitted to all frontend pages rendered by the builder via wp_localize_script, meaning any unauthenticated visitor can trivially retrieve a valid nonce from page source and satisfy the only access control in place.

Technical Analysis
CVE-2026-75027 is an authorization bypass vulnerability in the Themify Builder WordPress plugin affecting all versions up to and including 7.8.0. The plugin fails to properly verify user authorization before allowing modification of stored styling data (padding and margin properties) for posts. An attacker can supply a controlled post ID and JSON styling payload to alter styling on arbitrary posts, including private and draft posts. The nonce intended to protect this action is exposed to all frontend pages via wp_localize_script, allowing unauthenticated users to obtain a valid nonce and bypass the only access control mechanism.
Potential Impact
An unauthenticated attacker can modify the styling data of any post, including private and draft posts, potentially altering site appearance or content presentation without authorization. There is no direct confidentiality or availability impact reported, but integrity of post styling is compromised.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, restrict access to the affected plugin or disable it if possible to prevent exploitation. Monitor official Themify channels for updates and apply any official fixes once released.
