CVE-2026-3681

6.3 MEDIUM

📋 TL;DR

This vulnerability allows remote attackers to perform server-side request forgery (SSRF) attacks against welovemedia FFmate versions up to 2.0.15. Attackers can manipulate the fireWebhook function to make the server send unauthorized requests to internal systems. Organizations using FFmate for media processing are affected.

💻 Affected Systems

Products:
  • welovemedia FFmate
Versions: Up to and including 2.0.15
Operating Systems: All platforms running FFmate
Default Config Vulnerable: ⚠️ Yes
Notes: All deployments with the vulnerable webhook function are affected regardless of configuration.

⚠️ 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).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could pivot to internal systems, access sensitive data, perform internal reconnaissance, or execute commands on internal services via SSRF.

🟠

Likely Case

Attackers scan internal networks, access metadata services, or interact with internal APIs to steal information or disrupt services.

🟢

If Mitigated

Limited to unsuccessful SSRF attempts with proper network segmentation and input validation in place.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Public exploit available on GitHub, remote attack vector, and vendor unresponsive increase weaponization likelihood.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: None available

Restart Required: No

Instructions:

No official patch available. Consider workarounds or alternative software.

🔧 Temporary Workarounds

Network Segmentation

linux

Restrict outbound network access from FFmate servers to only necessary destinations.

iptables -A OUTPUT -p tcp --dport 80 -j DROP
iptables -A OUTPUT -p tcp --dport 443 -j DROP

Input Validation

all

Implement strict URL validation in the fireWebhook function to reject internal IPs and localhost.

🧯 If You Can't Patch

  • Disable or restrict webhook functionality entirely if not needed.
  • Deploy a web application firewall (WAF) with SSRF protection rules.

🔍 How to Verify

Check if Vulnerable:

Check FFmate version; if ≤2.0.15, it's vulnerable. Review webhook logs for suspicious outbound requests.

Check Version:

Check application configuration or deployment manifest for version information.

Verify Fix Applied:

Test SSRF attempts against the webhook endpoint; successful blocks indicate mitigation.

📡 Detection & Monitoring

Log Indicators:

  • Unusual outbound HTTP requests from FFmate server to internal IPs
  • Webhook requests with unusual URLs or internal addresses

Network Indicators:

  • Outbound connections from FFmate to unexpected internal services
  • HTTP requests to metadata endpoints (169.254.169.254)

SIEM Query:

source="ffmate.log" AND (url CONTAINS "localhost" OR url CONTAINS "127.0.0.1" OR url CONTAINS "169.254.169.254")
