Vulnerability Title
Spam protection, Honeypot, Anti-Spam by CleanTalk <= 6.86 - Unauthenticated Stored Cross-Site Scripting via Comment Content aria-label Placeholder
Source: CVE Program / CVE List V5
Vulnerability Description
The Spam protection, Honeypot, Anti-Spam by CleanTalk plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content aria-label Placeholder in all versions up to, and including, 6.86 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with custom-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload is deliverable via unauthenticated comment submission and executes exclusively for non-logged-in visitors; if comment moderation is enabled, an approving moderator must first publish the comment before the script reaches other users.
