⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, take over the WordPress site, install backdoors, or redirect all visitors to malicious sites, potentially leading to complete site compromise and data theft.
Likely Case
Attackers steal user session cookies or authentication tokens, allowing them to impersonate users, modify content, or access sensitive information within the WordPress dashboard.
If Mitigated
With proper input validation and output encoding, malicious scripts would be neutralized before execution, preventing any client-side code injection.
🎯 Exploit Status
DOM-based XSS requires specific user interaction or crafted inputs to trigger, making exploitation more complex than reflected XSS.
