⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, redirect users to malicious sites, or perform actions on behalf of authenticated users, potentially leading to account compromise or data theft.
Likely Case
Attackers inject malicious scripts that execute in users' browsers, potentially stealing session tokens or displaying phishing content to users interacting with the Ask module.
If Mitigated
With proper input validation and output encoding, the malicious scripts would be neutralized, preventing execution in users' browsers.
🎯 Exploit Status
The exploit is publicly available and can be executed remotely without authentication. Attack complexity is low as it involves simple script injection.
