mongodb fixed: 3.2.5 
Upgrade mongodb to 3.2.5
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for mongodb

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-11695, inspect your project dependencies for Mongodb:

inspect dependencies for mongodb

Analyze the terminal output to locate any version of Mongodb in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.2.5), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details
