Quantumcloud · Wpbot – Ai Chatbot For Live Support · CVE-2026-83593
**Name of the Vulnerable Software and Affected Versions**
WPBot – AI ChatBot for Live Support, Lead Generation, AI Services versions prior to 8.7.4
**Description**
Insufficient input sanitization and output escaping allow unauthenticated attackers to perform Stored Cross-Site Scripting (XSS), a technique where malicious scripts are permanently stored on a target server. The issue occurs via the `conversation` parameter. Because the nonce used for validation is localized into every public-facing page via `wp localize script`, it fails to act as an effective access control barrier, allowing the injected scripts to execute when a user accesses the affected page.
**Recommendations**
Update WPBot – AI ChatBot for Live Support, Lead Generation, AI Services to version 8.7.4 or later.
Avoid using the `conversation` parameter until the plugin is updated.
