CVE-2026-8199 (GCVE-0-2026-8199)

Vulnerability from cvelistv5 – Published: 2026-05-13 00:05 – Updated: 2026-05-13 14:34
VLAI
Title
Post-auth memory exhaustion via bitwise match expressions
Summary
An authenticated user can cause excess memory usage via bitwise match expression AST processing of $bitsAllSet, $bitsAnySet, $bitsAllClear, and $bitsAnyClear. This contributes to memory pressure and may lead to availability loss by OOM. This issue impacts MongoDB Server v7.0 versions prior to 7.0.34, v8.0 versions prior to 8.0.23, v8.2 versions prior to 8.2.9 and v8.3 versions prior to 8.3.2.

Mitigation

Phase: Implementation

Description:

  • Ensure multiple allocations of the same kind of object are properly tracked - possibly across multiple sessions, requests, or messages. Define an appropriate strategy for handling requests that exceed the limit, and consider supporting a configuration option so that the administrator can extend the amount of memory to be used if necessary.
Mitigation

Phase: Operation

Description:

  • Run the program using system-provided resource limits for memory. This might still cause the program to crash or exit, but the impact to the rest of the system will be minimized.
CAPEC-130: Excessive Allocation

An adversary causes the target to allocate excessive resources to servicing the attackers' request, thereby reducing the resources available for legitimate services and degrading or denying services. Usually, this attack focuses on memory allocation, but any finite resource on the target could be the attacked, including bandwidth, processing cycles, or other resources. This attack does not attempt to force this allocation through a large number of requests (that would be Resource Depletion through Flooding) but instead uses one or a small number of requests that are carefully formatted to force the target to allocate excessive resources to service this request(s). Often this attack takes advantage of a bug in the target to cause the target to allocate resources vastly beyond what would be needed for a normal request.
