AI Analysis
Technical Summary
This vulnerability (CVE-2026-13058) in MongoDB Server involves a reachable assertion failure (CWE-617) triggered by an authenticated user with basic write privileges. By sending a crafted transaction command with an incomplete set of required fields, the mongod process encounters inconsistent validation across related transaction parameters, causing a fatal internal invariant failure that terminates the process abnormally. This results in a denial of service condition. The affected versions are specifically 8.0, 8.2.0, and 8.3.0. There is no vendor advisory or patch currently available to address this issue.
Potential Impact
An authenticated user with basic write privileges can cause the MongoDB server process to terminate unexpectedly, resulting in denial of service. This disrupts availability of the database service. There is no indication of privilege escalation or data compromise from the provided information.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to trusted users only and monitor for unusual transaction commands. No official fix or workaround has been published by MongoDB at this time.
