What is CVE-2026-6393?

CVE-2026-6393 is a medium-severity missing authorization vulnerability in wpdevteam BetterDocs – Knowledge Base Docs & FAQ Solution for Elementor & Block Editor, published on 24 Apr 2026. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

The BetterDocs plugin for WordPress is vulnerable to Missing Authorization in versions up to and including 4.3.11. This is due to a missing capability check in the generate_openai_content_callback() function, which relies solely on a nonce rather than verifying user permissions. This makes it possible for authenticated attackers, with subscriber-level access and above, to trigger OpenAI API calls using the site's configured API key with arbitrary user-controlled prompts, leading to unauthorized consumption of the site owner's paid AI API quota.
