Published Apr 24, 2026 CWE-862 EPSS 0.27% (19th pctl)

Overview

CVE-2026-6393 is a medium-severity vulnerability. It was published on April 24, 2026 and has a CVSS 3.1 base score of 4.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.3, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
