- 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 system compromise with attacker gaining complete control over the developer's machine, potentially leading to lateral movement within the network, data theft, and ransomware deployment.
Likely Case
Local privilege escalation allowing attackers to execute commands with the privileges of the VSCode user, potentially accessing sensitive development files, credentials, and source code.
If Mitigated
Limited impact with proper network segmentation and least privilege principles, potentially isolated to the developer's workstation without network access.
🎯 Exploit Status
Exploitation requires the attacker to have some level of access to the developer's VSCode environment, either through social engineering, compromised accounts, or malicious extensions.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check the Spring Security advisory for specific version
Vendor Advisory: https://spring.io/security/cve-2026-22718
Restart Required: Yes
Instructions:
1. Open Visual Studio Code. 2. Go to Extensions view (Ctrl+Shift+X). 3. Find Spring CLI extension. 4. Click Update or reinstall from marketplace. 5. Restart VSCode after update.
🔧 Temporary Workarounds
Disable Spring CLI Extension
allTemporarily disable the vulnerable extension until patched
code --disable-extension vscjava.vscode-spring-cli
Remove Extension
allCompletely uninstall the vulnerable extension
code --uninstall-extension vscjava.vscode-spring-cli
🧯 If You Can't Patch
- Implement strict network segmentation for developer workstations
- Apply principle of least privilege to developer accounts and restrict command execution capabilities
🔍 How to Verify
Check if Vulnerable:
Check VSCode extensions for Spring CLI version. If using a version prior to the patched release, you are vulnerable.Check Version:
code --list-extensions --show-versions | grep spring-cliVerify Fix Applied:
Verify the Spring CLI extension version in VSCode extensions panel matches or exceeds the patched version mentioned in the Spring Security advisory.📡 Detection & Monitoring
