CVE-2026-18692

Summary: CVE-2026-18692 affects MongoDB Server, specifically its timeseries bucket lifecycle handling. An authenticated user with write privileges can trigger a use-after-free condition in internal memory after a reference is freed, which could cause a server crash or, potentially, execution of u...

Use-After-Free in MongoDB Timeseries Bucket Handling Leads to Denial of Service and Potential Remote Code Execution

An issue in MongoDB Server's handling of timeseries bucket lifecycle could allow an authenticated user with write privileges to cause an internal reference to be used after the underlying memory has been freed. Subsequent operations could then result in a server crash or, potentially, execution o...

CVE-2026-18692: Use After Free

An issue in MongoDB Server's handling of timeseries bucket lifecycle could allow an authenticated user with write privileges to cause an internal reference to be used after the underlying memory has been freed. Subsequent operations could then result in a server crash or, potentially, execution o...

CVE-2026-18693: Out-of-bounds Write

An issue in MongoDB Server's handling of timeseries collections could allow an authenticated user with write privileges to cause an internal data structure to become inconsistent through certain document insertions. A subsequent insert into the affected bucket could then result in the server...

BIT-MONGODB-2026-9748 $_internalConvertBucketIndexStats may crash the mongod server when working on no timeseries input

The $internalConvertBucketIndexStats stage used PauseExecution as a way to signal "skip this document" when an index stats conversion failed. But PauseExecution is not a general purpose skip mechanism, but rather a TeeBuffer-internal signal used solely by $facet to coordinate its sub-pipelines...

CVE-2026-9748

The CVE-2026-9748 issue affects MongoDB’s mongod when the $_internalConvertBucketIndexStats stage is used before $facet. It treats PauseExecution as an internal TeeBuffer signal rather than a general skip, causing an invariant assertion and a crash when processing no timeseries input. The descrip...
