⚠️ Risk & Real-World Impact
Worst Case
Attackers could inject persistent malicious scripts that execute in visitors' browsers, potentially stealing session cookies, redirecting users to malicious sites, or performing actions on behalf of authenticated users.
Likely Case
Attackers trick authenticated administrators into clicking malicious links that modify plugin settings to inject JavaScript payloads, affecting all site visitors.
If Mitigated
With proper CSRF protections and input validation, the vulnerability would be prevented from being exploited.
🎯 Exploit Status
Exploitation requires social engineering to trick authenticated users into performing actions. The CSRF leads to stored XSS payload injection.
