BetterDocs vulnerabilities

The BetterDocs plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Heading 'id' Attribute in Post Content in all versions up to and including 4.8.1 due to insufficient input sanitization and output escaping. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages that execute whenever a user accesses the page.

The BetterDocs plugin version 4.6.2 and earlier has a Cross-Site Scripting (XSS) vulnerability for users with the Contributor role. A Contributor can inject malicious JavaScript code.

The BetterDocs WordPress plugin before version 4.5.5 does not sanitize an AI-generated documentation summary before storing and outputting it. The feature is exposed to unauthenticated users, allowing them to store a malicious payload via prompt injection that executes in the browser of any visitor, including administrators.

The BetterDocs plugin for WordPress up to version 4.6.0 is vulnerable to generic SQL injection via the 'lang' parameter. Authenticated attackers with custom-level access or higher can append additional SQL queries, allowing extraction of sensitive database information. Exploitation requires an active multilingual plugin (WPML, Polylang, qTranslate, Weglot, or TranslatePress).

The BetterDocs plugin for WordPress in versions up to and including 4.3.10 exposes sensitive system information to an unauthorized control sphere, allowing retrieval of embedded sensitive data.
