⚠️ Risk & Real-World Impact
Worst Case
Complete service unavailability through resource exhaustion or application crashes, potentially affecting all users of the vulnerable Redoc instance.
Likely Case
Temporary service disruption or degraded performance when attackers send crafted payloads to trigger the prototype pollution.
If Mitigated
Minimal impact with proper input validation and sanitization in place, though the underlying vulnerability remains.
🎯 Exploit Status
Exploitation requires sending crafted payloads to trigger prototype pollution in the mergeObjects function.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: > 2.2.0
Vendor Advisory: https://github.com/Redocly/redoc/issues/2499
Restart Required: No
Instructions:
1. Update Redoc to version 2.2.1 or later. 2. Run npm update redoc or yarn upgrade redoc. 3. Rebuild and redeploy your application.
🔧 Temporary Workarounds
Input Validation
allImplement strict input validation and sanitization for all data passed to Redoc's mergeObjects function.
🧯 If You Can't Patch
- Implement WAF rules to block suspicious payloads targeting the mergeObjects function.
- Isolate Redoc instances behind reverse proxies with rate limiting and request filtering.
🔍 How to Verify
Check if Vulnerable:
Check package.json or run npm list redoc to verify installed version is <= 2.2.0.Check Version:
npm list redoc | grep redocVerify Fix Applied:
Confirm Redoc version is > 2.2.0 using npm list redoc or checking package.json.📡 Detection & Monitoring
