CVE-2026-13058: CWE-617: Reachable Assertion in MongoDB MongoDB Server
CVE-2026-13058 is a high-severity vulnerability in MongoDB Server where an authenticated user with basic write privileges can cause the mongod process to crash by sending a crafted transaction command missing required fields. This leads to a denial of service due to an internal assertion failure caused by inconsistent validation of transaction command parameters.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-13058) affects MongoDB Server versions 8.0, 8.2.0, and 8.3.0. It arises from inconsistent validation of related transaction command parameters, allowing an authenticated user with basic write privileges to send a crafted transaction command with incomplete required fields. This triggers a fatal internal invariant failure (reachable assertion) in the mongod process, causing it to terminate abnormally and resulting in denial of service. The CVSS 4.0 base score is 7.1, indicating high severity with network attack vector, low attack complexity, no user interaction, and requiring low privileges.
Potential Impact
An attacker with basic write privileges can cause the MongoDB server process (mongod) to crash, resulting in denial of service. This disrupts availability of the database service but does not indicate data confidentiality or integrity compromise based on the provided information.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation is currently documented. Until a patch is available, restrict write privileges to trusted users only and monitor for abnormal mongod process terminations.
