⚠️ Risk & Real-World Impact
Worst Case
Attackers execute arbitrary JavaScript in victims' browsers, potentially stealing session cookies, performing actions as authenticated users, or redirecting to malicious sites.
Likely Case
Limited XSS attacks stealing user data or performing unauthorized actions within the vulnerable application context.
If Mitigated
No impact with proper input validation, output encoding, and Content Security Policy implementation.
🎯 Exploit Status
XSS exploitation typically requires user interaction but can be automated via phishing or stored XSS.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.0.0
Vendor Advisory: https://github.com/gurgunday/ghtml/security/advisories/GHSA-vvhj-v88f-5gxr
Restart Required: No
