⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator session cookies, take over WordPress sites, deface websites, or redirect users to malicious sites, potentially leading to complete site compromise and data theft.
Likely Case
Attackers inject malicious JavaScript that steals user session cookies or credentials when users view compromised pages, leading to account takeover of regular users or administrators.
If Mitigated
With proper input validation and output encoding, malicious scripts would be neutralized before reaching users, preventing execution even if injection attempts occur.
🎯 Exploit Status
Stored XSS vulnerabilities are commonly exploited, and proof-of-concept details are publicly available. Exploitation typically requires some level of user interaction or access.
