CVE-2024-21571
📋 TL;DR
A remote code execution vulnerability in Snyk Code Agent allows attackers to execute arbitrary code within the container. All versions of Code Agent are affected. Exploitation requires network access to the Code Agent within the deployment environment.
💻 Affected Systems
- Snyk Code Agent
⚠️ 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).

- Review the CVE details at 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
Full compromise of the Code Agent container leading to lateral movement within the cluster, data exfiltration, and persistent backdoor installation.
Likely Case
Limited container compromise if proper network segmentation and security controls are in place, potentially allowing reconnaissance and limited data access.
If Mitigated
No impact with proper network segmentation, least privilege configurations, and updated versions.
🎯 Exploit Status
Exploitation requires network access to the Code Agent and may depend on cluster misconfigurations or chaining with other vulnerabilities.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Snyk documentation for latest patched version
Vendor Advisory: https://www.cve.org/CVERecord?id=CVE-2024-21571
Restart Required: Yes
Instructions:
1. Update Snyk Code Agent to the latest version
2. Restart the Code Agent container
3. Verify the update was successful
🔧 Temporary Workarounds
Network Segmentation
allRestrict network access to Code Agent containers using network policies or firewall rules
# Example Kubernetes NetworkPolicy to restrict access
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
name: snyk-code-agent-policy
spec:
podSelector:
matchLabels:
app: snyk-code-agent
policyTypes:
- Ingress
ingress:
- from:
- podSelector:
matchLabels:
app: snyk-monitor
ports:
- protocol: TCP
port: 3000
Least Privilege Configuration
allRun Code Agent containers with minimal privileges and capabilities
docker run --read-only --cap-drop=ALL snyk/code-agent
# Or in Kubernetes:
securityContext:
readOnlyRootFilesystem: true
capabilities:
drop:
- ALL
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Code Agent containers
- Apply least privilege principles to container configurations and runtime
🔍 How to Verify
Check if Vulnerable:
Check if running any version of Snyk Code Agent; all versions are vulnerableCheck Version:
Check container image tag or run: docker inspect <container_id> | grep -i versionVerify Fix Applied:
Verify Code Agent version is updated to latest patched version and check container logs for successful startup📡 Detection & Monitoring
Log Indicators:
- Unusual process execution in Code Agent container
- Suspicious network connections to/from Code Agent
- Unexpected container restarts or crashes
Network Indicators:
- Unusual traffic patterns to Code Agent ports
- Connection attempts from unauthorized sources to Code Agent
SIEM Query:
container.runtime.name="*snyk*" AND (process.name="sh" OR process.name="bash" OR process.name="python")
