Description
An issue in MongoDB Server's geospatial query processing could allow an authenticated user with write privileges to cause certain malformed geometry data to be stored and later processed without proper validation. Subsequent queries against this data could then result in the server accessing memory outside its intended bounds. This could result in a server crash (denial of service) and may expose a limited amount of server process memory.

Impact

An authenticated user with write privileges to MongoDB Server can insert malformed geometry data that is later processed by the geospatial query engine. During processing, the server may access memory beyond its bounds, leading to an out-of-bounds read. This can cause the server to crash, resulting in a denial of service, and may expose a limited portion of server process memory. The weakness is aligned with CWE‑125, which denotes out-of-bounds memory reads.

Affected Systems

MongoDB Server is affected. The vulnerability impacts versions prior to the fix for ticket SERVER‑130188. Specific version ranges are not disclosed in the advisory, so all installations of MongoDB Server that have not applied the latest security patches are susceptible.

Risk and Exploitability

The CVSS score of 7.1 classifies the issue as high severity, while an EPSS score of less than 1 % indicates a very low probability of exploitation in the wild at the time of analysis. Because the vulnerability requires authenticated write access, attackers must compromise a legitimate account; otherwise, the attack is not feasible. The absence from the CISA KEV list suggests that targeted exploitation is not yet known, but the potential for denial of service and memory disclosure still warrants prompt action.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update MongoDB Server to the latest released version that contains the fix for SERVER‑130188, ensuring the geospatial query processing logic is patched.
  • Limit write privileges of authenticated users to restrict the ability to insert malformed geometry data; apply the principle of least privilege.
  • Monitor server logs for abnormal crashes or memory access errors, and configure alerting for service availability to detect potential exploitation attempts.
  • If geospatial features are not required, consider disabling them to remove the attack surface.
