CVE-2026-25609
📋 TL;DR
This MongoDB vulnerability allows authenticated users to bypass intended read-only restrictions on the 'filter' parameter in profile commands, potentially modifying database behavior. It affects MongoDB servers with profile commands enabled, requiring attacker authentication.
💻 Affected Systems
- MongoDB Server
📦 What is this software?
Mongodb by Mongodb

⚠️ Risk & Real-World Impact
Worst Case
Authenticated attackers could manipulate database profiling filters to bypass security controls, potentially enabling data exfiltration or unauthorized access to restricted data.
Likely Case
Authenticated users with profile command access could alter profiling behavior to monitor or interfere with database operations they shouldn't have access to.
If Mitigated
With proper authentication controls and limited profile command access, impact is minimal as only authorized users could exploit this.
🎯 Exploit Status
Exploitation requires authenticated access to MongoDB with profile command permissions.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check MongoDB security advisory for specific fixed versions
Vendor Advisory: https://jira.mongodb.org/browse/SERVER-112952
Restart Required: Yes
Instructions:
1. Check MongoDB security advisory for affected versions. 2. Upgrade to patched version. 3. Restart MongoDB service. 4. Verify fix with version check.
🔧 Temporary Workarounds
Disable Profile Commands
allDisable database profiling if not required for operations
db.setProfilingLevel(0)
Restrict Profile Command Access
allLimit which users/roles can execute profile commands
Use MongoDB role-based access control to restrict 'profile' command permissions
🧯 If You Can't Patch
- Implement strict authentication and authorization controls for MongoDB access
- Monitor and audit profile command usage for suspicious activity
🔍 How to Verify
Check if Vulnerable:
Check MongoDB version against affected versions in security advisoryCheck Version:
db.version()Verify Fix Applied:
Verify MongoDB version is updated to patched version and test profile command restrictions📡 Detection & Monitoring
Log Indicators:
- Unauthorized or unexpected profile command usage
- Profile filter modifications by unauthorized users
Network Indicators:
- Profile command requests with filter modifications
