CVE-2026-115929 is a high-severity vulnerability in MongoDB Compass caused by improper certificate validation due to the inclusion of recoverable eMudhra intermediate CA certificates in the Electron runtime's TLS root certificate store. This issue is resolved by updating to Compass version 1.53.1, which includes Electron 44.9.1.
In MongoDB Controllers for Kubernetes, insufficient validation of Ops Manager backup configuration may allow a user who can modify an OpsManager custom resource to cause unintended administrative changes in Ops Manager. This affects deployments using Enterprise Ops Manager backup reconciliation.
Prototype pollution in csv parsing logic during import can lead to untrusted file paths (but not arguments) entering shell.openExternal after specific user behavior leading to "1-click" command execution.
The MongoDB C Driver's legacy GridFS API accepts malformed file metadata from the database without adequate validation. Crafted documents in a GridFS collection may cause any application that reads those files via the legacy API to either crash (via a division-by-zero) or silently leak process memory contents (via an out-of-bounds read).
Creating a "2dsphere_bucket" index on a non-timeseries bucket collection will succeed, but any subsequent attempt to insert a document which triggers updating that index will crash the server. A similar issue occurs when creating "queryable_encrypted_range" indices.
This issue affects MongoDB Server v7.0 versions prior to 7.0.32, v8.0 versions prior to 8.0.21 and v8.2 versions prior to 8.2.6
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.
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.
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.
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.
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 is a high-severity vulnerability in MongoDB Server's time-series collection implementation. It allows an authenticated user with database write privileges to cause an out-of-bounds memory write in the mongod process due to an inconsistency in the internal field-name-to-index mapping within the time-series bucket catalog. This flaw can lead to arbitrary code execution under certain conditions. The vulnerability affects multiple MongoDB Server versions prior to 5.0.33, 6.0.28, 7.0.34, 8.
An administrative user with access to configure webhooks can execute arbitrary commands by configuring and then triggering webhooks containing specific FreeMarker template syntax.
This issue affects all MongoDB Ops Manager 7.0 versions and MongoDB Ops Manager versions 8.0.22 and prior.
