CVE-2026-8199 Details
Description
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.
A denial-of-service vulnerability has been identified in MongoDB Server versions 7.0 prior to 7.0.34, 8.0 prior to 8.0.23, 8.2 prior to 8.2.9, and 8.3 prior to 8.3.2. This vulnerability allows an authenticated user to cause excessive memory consumption by exploiting bitwise match expression AST processing of $bitsAllSet, $bitsAnySet, $bitsAllClear, and $bitsAnyClear. The increased memory usage creates memory pressure that may result in availability loss due to out-of-memory conditions.
Users can upgrade to MongoDB Server versions 8.2.8, 8.0.22, 7.0.33, 8.3.0-rc4, 8.2.9, 8.0.23, 8.2.10, or 8.0.24 to address this vulnerability.
