CVE-2026-23880
📋 TL;DR
OnboardLite versions before commit 1d32081a66f21bcf41df1ecb672490b13f6e429f contain a stored cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts into the admin dashboard. When an admin attempts to migrate a user's Discord account, the malicious script executes in the admin's browser context. This affects all users running vulnerable versions of OnboardLite.

⚠️ Risk & Real-World Impact
Worst Case
An attacker could steal admin session cookies, perform actions as the admin (like modifying user data or system settings), or redirect to phishing sites.
Likely Case
Attackers could hijack admin sessions to access sensitive user information or perform unauthorized administrative actions.
If Mitigated
With proper input validation and output encoding, the malicious script would be rendered harmless as text rather than executable code.
🎯 Exploit Status
Exploitation requires the attacker to have some level of access to inject malicious payloads, and then an admin must trigger the vulnerable functionality.

🔍 How to Verify
Check if Vulnerable:
Check if your OnboardLite installation includes commit 1d32081a66f21bcf41df1ecb672490b13f6e429f. If not, you are vulnerable.Check Version:
git log --oneline | head -1Verify Fix Applied:
After applying the patch, test the Discord account migration functionality with a benign XSS payload (e.g., <script>alert('test')</script>) to ensure it's properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual or malformed input in Discord migration API requests
- Admin session cookies being accessed from unexpected IP addresses
Network Indicators:
- HTTP requests containing script tags or JavaScript code in Discord migration parameters
