CVE-2026-18701 is a vulnerability in MongoDB Server's query subsystem that allows an authenticated user with read privileges to cause the server process to terminate unexpectedly by submitting a specially crafted query filter. This results in a denial of service condition. The vulnerability does not impact confidentiality or integrity but affects availability.
AI Analysis
Technical Summary
This vulnerability in MongoDB Server arises from improper handling of query filters in the query subsystem. An authenticated user with read privileges can exploit this flaw by submitting a specially formed query filter, causing the server process to crash unexpectedly. This leads to denial of service (DoS) without affecting data confidentiality or integrity. The CVSS 3.1 base score is 6.5 (High), reflecting the network attack vector, low attack complexity, required privileges of read access, no user interaction, and impact limited to availability.
Potential Impact
An attacker with read privileges can cause the MongoDB server process to terminate unexpectedly, resulting in denial of service. There is no impact on confidentiality or integrity of data. The service disruption could affect availability of the database to legitimate users.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch or official fix is available, monitor for unusual server terminations and restrict read privileges to trusted users only.
