Blogchat Chat System
Monthly
Cross-Site Request Forgery in the BLOGCHAT Chat System WordPress plugin (all versions through 1.3.6.3) enables unauthenticated remote attackers to both update plugin settings and inject persistent malicious web scripts by tricking an authenticated site administrator into clicking a crafted link. The vulnerability stems from missing or incorrect nonce validation across multiple functions in wp-blogchat-widget.php (lines 208, 215, 222, 293), making it a compound CSRF+Stored XSS risk with Changed scope (S:C) in the CVSS rating. No public exploit code or CISA KEV listing has been identified at time of analysis.
