Description
Themify Builder plugin for WordPress up to version 7.8.0 has an authorization bypass vulnerability. This flaw allows unauthenticated attackers to modify styling data of arbitrary posts, including private and draft posts, by exploiting improper authorization checks. The vulnerability arises because a nonce required for access control is exposed to all frontend pages, enabling trivial retrieval by attackers.

Technical Analysis
CVE-2026-75027 is an authorization bypass vulnerability (CWE-862) in Themify Builder plugin for WordPress 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 post ID and JSON styling payload to modify arbitrary posts, including private and draft posts. The nonce used for access control is automatically emitted to all frontend pages via wp_localize_script, allowing unauthenticated users to retrieve a valid nonce and bypass authorization controls.
Potential Impact
An unauthenticated attacker can modify the styling data of any post, including private and draft posts, potentially altering the appearance or layout of content without authorization. There is no impact on confidentiality or availability reported, but integrity of post styling data is compromised.
Mitigation Recommendations
No patch or official fix is currently documented. Users should monitor the vendor advisory for updates. Until a fix is available, consider restricting access to frontend pages or disabling the Themify Builder plugin if feasible to reduce exposure.
