CVE-2026-13056: CWE-1325: Improperly Controlled Sequential Memory Allocation in MongoDB MongoDB Server
Using expressions that generate large arrays it is possible to craft a query that creates very large intermediate objects in memory, causing the server to crash with OOM error.
AI Analysis
Technical Summary
This vulnerability (CWE-1325) in MongoDB Server allows an attacker with low privileges to craft queries that produce very large intermediate arrays in memory. These large allocations are improperly controlled, causing the server process to exhaust available memory and crash with an OOM error. The issue affects specifically MongoDB Server versions 8.0 and 8.3.0. There is no vendor advisory or patch information currently available, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation results in denial of service by crashing the MongoDB server due to out-of-memory conditions. This can disrupt availability of database services but does not indicate direct data compromise or privilege escalation based on the provided information.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider limiting query complexity and monitoring for unusually large array operations that could trigger this condition. No official fix or temporary workaround has been published at this time.
