CVE-2023-5606: Quantumcloud Wpbot

Medium severity, CVSS 4.8. EPSS: 0.3% chance of exploitation in the next 30 days.

The ChatBot for WordPress is vulnerable to Stored Cross-Site Scripting via the FAQ Builder in versions 4.8.6 through 4.9.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled. NOTE: This vulnerability is a re-introduction of CVE-2023-4253.

Affected products

• Quantumcloud Wpbot: from 4.8.6, before 4.9.7 (fixed in 4.9.7)
