Vulnerability from cvelistv5 – Published: 2026-05-13 00:19 – Updated: 2026-05-13 01:38

Title

Post-authentication CPU utilization DoS via $trim/$ltrim/$rtrim operators

Summary

Using a densely populated chars mask and a large input string in the MongoDB aggregation operators $trim, $ltrim, and $rtrim, an authenticated user with aggregation permissions can pin CPU utilization at 100% for an extended period of time. 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.

CVE-2026-8336 (GCVE-0-2026-8336)

Vulnerability from cvelistv5 – Published: 2026-05-13 00:16 – Updated: 2026-05-15 16:16

Title

Post-authentication use-after-free error in $_internalJsEmit and mapreduce commands

Summary

After invoking $_internalJsEmit, which is not intended to be directly accessible, or mapreduce command’s map function in a certain way, an authenticated user can subsequently crash mongod when the server-side JavaScript engine (through $where, $function, mapreduce reduce stage, etc.) is used also in a specific way, resulting in a post-authentication denial-of-service. This issue impacts MongoDB Server v8.2 versions prior to 8.2.9 and v8.3 versions prior to 8.3.2.

CVE-2026-8201 (GCVE-0-2026-8201)

Vulnerability from cvelistv5 – Published: 2026-05-13 00:12 – Updated: 2026-05-13 14:34

Title

Use-After-Free in MongoDB FLE Query Analysis When Processing Positional Projections on Encrypted Fields

Summary

A use-after-free vulnerability exists in MongoDB's Field-Level Encryption (FLE) query analysis component, affecting client-side uses of mongocryptd and crypt_shared. Triggering this vulnerability requires control over the structure of a client's FLE-related query. This issue impacts MongoDB Server’s mongocryptd component 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.

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

Vulnerability from cvelistv5 – Published: 2026-05-13 00:05 – Updated: 2026-05-13 14:34

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.

CVE-2026-8053 (GCVE-0-2026-8053)

Vulnerability from cvelistv5 – Published: 2026-05-12 23:59 – Updated: 2026-05-14 03:56

Title

FlatBSON Duplicate Field Index Drift

Summary

An issue in MongoDB Server's time-series collection implementation allows an authenticated user with database write privileges to trigger an out-of-bounds memory write in the mongod process. The issue results from an inconsistency in the internal field-name-to-index mapping within the time-series bucket catalog. Under certain conditions this can result in arbitrary code execution. This issue impacts MongoDB Server v5.0 versions prior to 5.0.33, v6.0 versions prior to 6.0.28, 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.
