What is CVE-2025-12180?
CVE-2025-12180 is a medium-severity missing authorization vulnerability in qodeinteractive Qi Blocks, published on 1 Nov 2025. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The Qi Blocks plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.4.3. This is due to the plugin storing arbitrary CSS styles submitted via the `qi-blocks/v1/update-styles` REST API endpoint without proper sanitization in the `update_global_styles_callback()` function. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary CSS, which can be used to perform actions such as hiding content, overlaying fake UI elements, or exfiltrating sensitive information via CSS injection techniques.
