CVE-2026-82076: CWE-190: Integer Overflow or Wraparound in MongoDB MongoDB Server
An integer overflow in the query planning component of MongoDB Server can allow an authenticated user with ordinary database-level read/write privileges to bypass an internal resource limit. Submitting a specially crafted query causes the server to consume memory without bound during query planning, and the resulting exhaustion terminates the server process. This may result in a denial of service affecting all databases served by the affected node.
AI Analysis
Technical Summary
This vulnerability involves an integer overflow (CWE-190) in MongoDB Server's query planning component. When exploited by an authenticated user with standard database privileges, it allows bypassing of internal resource limits, causing the server to consume memory without bound during query planning. The resulting memory exhaustion terminates the server process, causing denial of service impacting all databases served by the affected node. The affected versions explicitly identified are 7.0.0, 8.0.0, and 8.3.0. The CVSS 4.0 score is 7.1 (high severity), reflecting network attack vector, low attack complexity, no user interaction, and high impact on availability. There is no vendor advisory or patch information provided, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation results in denial of service by causing the MongoDB server process to terminate due to unbounded memory consumption during query planning. This affects availability of all databases served by the affected MongoDB node. The attacker requires only ordinary database-level read/write privileges and no additional user interaction is needed.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider restricting access to trusted users only and monitoring for unusual query patterns that could trigger this vulnerability. No official patch or workaround is currently documented.
