CVE-2025-46749
📋 TL;DR
This is a cross-site scripting (XSS) vulnerability in SEL software where authenticated users can inject malicious scripts into improperly sanitized input fields. The scripts execute in other users' browsers when they view the affected content. This affects users of SEL software with authenticated access to vulnerable versions.
💻 Affected Systems
- SEL software products (specific products not detailed in reference)
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
An attacker could steal session cookies, perform actions as other users, deface interfaces, or redirect users to malicious sites.
Likely Case
Session hijacking, credential theft, or limited data exfiltration from authenticated users' browsers.
If Mitigated
Minimal impact with proper input validation, output encoding, and Content Security Policy (CSP) headers in place.
🎯 Exploit Status
Exploitation requires authenticated access and knowledge of vulnerable fields; typical XSS techniques apply.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Latest software versions (specific version not detailed)
Vendor Advisory: https://selinc.com/products/software/latest-software-versions/
Restart Required: Yes
Instructions:
1. Visit the SEL software versions page. 2. Identify and download the latest version for your product. 3. Follow vendor installation procedures. 4. Restart the application/service as required.
🔧 Temporary Workarounds
Implement Input Validation
allAdd server-side validation to reject or sanitize script-containing input in user-submitted fields.
Enable Content Security Policy
allConfigure CSP headers to restrict script execution sources and mitigate XSS impact.
🧯 If You Can't Patch
- Restrict user permissions to minimize who can submit content to vulnerable fields.
- Monitor and audit user-submitted content for suspicious scripting patterns.
🔍 How to Verify
Check if Vulnerable:
Test input fields for XSS by submitting safe payloads (e.g., <script>alert('test')</script>) and checking if they execute in other users' views.Check Version:
Check software version via application interface or vendor documentation; command varies by product.Verify Fix Applied:
After patching, retest XSS payloads to confirm they are properly sanitized or blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual user input containing script tags or JavaScript patterns in field submissions
Network Indicators:
- HTTP requests with script payloads in parameters or POST data
SIEM Query:
