| CVE-2026-8200 | When schema validation is enabled on a collection and an update or insert would violate the collection's schema, the local server log message generated may not have all user data redacted. 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. | [email protected] | 4.8 | 0.05% | 2026-05-13 | 2026-05-18 |
| CVE-2026-8199 | An authenticated user can cause excess memory usage via bitwise match expression AST processing of $bitsAllSet, $bitsAnySet, $bitsAllClear, and $bitsAnyClear.

| CVE-2026-8053 | 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 | [email protected] | 8.7 | 0.06% | 2026-05-13 | 2026-05-18 |
| CVE-2026-8063 | An authenticated user can crash mongod when running $rankFusion or $scoreFusion with an empty pipeline on a view. When resolving a view, the server inspects the aggregation pipeline to determine whether it begins with an Atlas Search stage. For $rankFusion and $scoreFusion, this inspection reads the first element on each stage’s input pipeline array without first verifying that the array is non-empty. Supplying an empty pipeline causes a null pointer dereference and crashes the server. This is | [email protected] | 7.1 | 0.05% | 2026-05-07 | 2026-05-11 |
| CVE-2026-6915 | An authorization flaw in the user management command could allow an authenticated user to make limited changes to authentication-related data associated with another user account. This could affect how authentication is performed for the impacted account. | [email protected] | 5.3 | 0.06% | 2026-04-29 | 2026-05-06 |
| CVE-2026-6914 | Computing the MD5 checksum of a malformed BSON object under specific conditions may cause loss of availability in MongoDB server.

| CVE-2026-6231 | The bson_validate function may return early on specific inputs and incorrectly report success. This behavior could result in skipping validation for BSON data, allowing malformed or invalid UTF-8 sequences to bypass validation and be processed incorrectly. The issue may affect applications that rely on these functions to validate untrusted BSON data before further processing.
