How can this vulnerability impact me? :
If exploited, this vulnerability can allow an attacker with administrator privileges to inject malicious scripts into your website. These scripts can execute in visitors' browsers, leading to unwanted redirects, displaying unauthorized advertisements, or other harmful actions that compromise the integrity and user experience of your site. [1]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
Detection of this vulnerability involves monitoring for malicious script injections by users with administrator privileges. Since the vulnerability allows stored Cross-Site Scripting (XSS), scanning for unusual or unauthorized script tags in the website content or database entries related to the CodePen Embed Block plugin is recommended. Professional incident response or server-side malware scanning is advised, as plugin-based malware scanners may be unreliable. Specific commands are not provided in the available resources. [1]
