⚠️ Risk & Real-World Impact
Worst Case
An attacker with compromised author credentials could inject malicious scripts that steal administrator credentials, deface websites, or redirect visitors to malicious sites, potentially affecting all site visitors.
Likely Case
Limited impact since exploitation requires author-level access; most likely used in targeted attacks against specific organizations or in conjunction with other vulnerabilities.
If Mitigated
With proper user access controls and content sanitization, impact is minimal as only trusted users can exploit the vulnerability.
🎯 Exploit Status
Exploitation requires author-level privileges, making it less accessible to external attackers without initial access.
