CVE-2023-5241: Quantumcloud Wpbot

High severity, CVSS 8.1. EPSS: 2.1% chance of exploitation in the next 30 days.

The AI ChatBot for WordPress is vulnerable to Directory Traversal in versions up to, and including, 4.8.9 as well as 4.9.2 via the qcld_openai_upload_pagetraining_file function. This allows subscriber-level attackers to append "<?php" to any existing file on the server resulting in potential DoS when appended to critical files such as wp-config.php.

Affected products

• Quantumcloud Wpbot: before 4.9.1 (fixed in 4.9.1); version 4.9.2 only
