CVE-2026-113870 MongoDB CVE debrief

Who should care

Defenders and administrators responsible for MongoDB Compass installations should assess exposure and prioritize verification and remediation. This includes reviewing the vulnerability's impact on their systems, verifying affected versions, and implementing compensating controls where necessary. Security teams and operators should also be aware of the potential risks and take steps to mitigate them.

Why it matters

Defenders should prioritize verifying and upgrading to a fixed version of MongoDB Compass, assessing exposure, and implementing compensating controls due to the risk of arbitrary code execution with user privileges.

• Arbitrary code execution with user privileges
• Potential for lateral movement and privilege escalation
• Need for verification of affected versions and remediation

Technical summary

MongoDB Compass improperly escapes certain BSON values when converting a stored view’s aggregation pipeline into editable source, allowing for arbitrary code execution with the privileges of the user running Compass. This vulnerability is significant because it can lead to arbitrary code execution, potentially allowing attackers to gain control of affected systems. The vulnerability is related to the improper encoding of server-supplied JavaScript values in BSON parsing, which can be exploited by specially crafted views.

Defensive priority

Defenders should prioritize verifying and upgrading to a fixed version of MongoDB Compass, assessing exposure, and implementing compensating controls.

Recommended defensive actions

• Verify and upgrade to a fixed version of MongoDB Compass
• Assess exposure and implement compensating controls
• Monitor for suspicious activity
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and source item provide details on the vulnerability, but limited information is available on affected versions and remediation. Defenders should verify the vulnerability's impact on their MongoDB Compass installations and assess exposure. Evidence from the CVE Program and NVD suggests that the vulnerability is significant but lacks detailed information on affected versions.
