CVE-2026-13073: CWE-617: Reachable Assertion in MongoDB MongoDB Server
CVE-2026-13073 is a medium severity vulnerability in MongoDB Server version 8.0 where an authenticated user with read-only privileges can cause the mongod process to crash by issuing a specially crafted aggregation command. This leads to a denial of service affecting all connected clients until the server process is restarted. The root cause is an internal engine selection inconsistency triggered by specific aggregation options.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-13073) affects MongoDB Server 8.0 and involves a reachable assertion (CWE-617) that can be triggered by an authenticated user with read-only access. By sending a crafted aggregation command with a particular combination of options, the internal engine selection logic becomes inconsistent, causing the mongod process to terminate abnormally. This results in a denial of service condition impacting all clients connected to the server until manual restart. There is no vendor advisory or patch information currently available, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation causes the MongoDB server process to crash, resulting in denial of service for all connected clients until the process is restarted. This can disrupt availability but does not escalate privileges or compromise data integrity or confidentiality based on the provided information.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit the issuance of aggregation commands by users with read-only privileges or monitor and restrict access to trusted users only. Restarting the mongod process restores service after a crash.
