MongoDB Aggregation Command Invariant Assertion Failure Leading to Process Termination (CVE-2026-13073)
CVE-2026-13073 is a vulnerability in MongoDB where an authenticated user with read-only privileges can cause the mongod process to terminate unexpectedly by sending a specially crafted aggregation command. This results in a denial of service affecting all connected clients until the process is restarted. The root cause is an internal inconsistency in engine selection triggered by specific aggregation options. A patch is available to address this issue.
AI Analysis
Technical Summary
This vulnerability allows an authenticated user with read-only access to trigger an invariant assertion failure within the MongoDB aggregation engine. By issuing a crafted aggregation command with a particular combination of options, the mongod process crashes, causing a denial of service. The issue is due to an internal engine selection inconsistency. The affected versions are MongoDB versions from 8.0.0 up to but not including 8.0.28. No known exploits are reported in the wild. A patch is available to fix this flaw.
Potential Impact
An attacker with read-only authentication privileges can cause the MongoDB server process to terminate unexpectedly, resulting in denial of service for all clients connected to that instance until the server is restarted. This disrupts availability but does not grant unauthorized data access or modification.
Mitigation Recommendations
A patch is available for this vulnerability. Users should upgrade MongoDB to version 8.0.28 or later to remediate this issue. Until patched, restricting access and monitoring for unusual aggregation command usage may help reduce risk.
