Summary
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).
Risk Assessment
The organization risks exposure of sensitive database data, including user passwords and API keys, potentially leading to account takeover and further compromise.
Recommendation
Immediately update the BetterDocs plugin to version 4.6.1 or later. If updating is not possible, temporarily disable multilingual support or restrict administrative access.

Original NVD description (English source)
The BetterDocs – AI Documentation, Knowledge Base, Docs, Wikis, FAQ with Chatbot plugin for WordPress is vulnerable to generic SQL Injection via the 'lang' parameter in all versions up to, and including, 4.6.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires a supported multilingual plugin (WPML, Polylang, qTranslate, Weglot, or TranslatePress) to be active on the site, as the vulnerable code path is gated by Helper::is_multilingual_active().
