⚠️ Risk & Real-World Impact
Worst Case
Attackers could inject persistent malicious scripts that steal administrator credentials, hijack user sessions, deface websites, or redirect visitors to malicious sites when administrators or users view compromised content.
Likely Case
Attackers trick administrators into performing actions that inject malicious JavaScript into website content, which then executes in visitors' browsers, potentially stealing cookies or session tokens.
If Mitigated
With proper CSRF protections and content sanitization, the attack would fail, preventing script injection and maintaining site integrity.
🎯 Exploit Status
Exploitation requires tricking authenticated users (particularly administrators) into clicking malicious links or visiting compromised pages. The CSRF leads to stored XSS payloads.
