CVE-2026-13731
HighCVSS 7.2Exploitation Probability (EPSS)
Low risk15th percentile — higher than 15% of all known CVEs
Summary
The WPBot – AI ChatBot plugin for WordPress up to version 8.4.9 is vulnerable to stored cross-site scripting via the 'conversation' parameter due to insufficient input sanitization and output escaping. Unauthenticated attackers can inject arbitrary web scripts that execute when users access affected pages. The AJAX nonce required for saving is publicly exposed on every frontend page, removing practical exploitation barriers.
Risk Assessment
The risk includes session hijacking, redirection to malicious sites, or theft of sensitive data without authentication. This could lead to administrator account takeover and full site compromise.
Recommendation
Update the WPBot plugin to the latest patched version immediately. If not possible, temporarily disable the plugin until the update is applied.
Original NVD description (English source)
The WPBot – AI ChatBot for Live Support, Lead Generation, AI Services plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'conversation' parameter in all versions up to, and including, 8.4.9 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The AJAX nonce required to authenticate the save request is publicly emitted on every frontend page via wp_localize_script, making it freely obtainable by any anonymous visitor and removing any practical barrier to exploitation.
