Detailsinfo

A vulnerability has been found in MongoDB Go Driver up to 1.1.x/2.8.x and classified as critical. This vulnerability affects an unknown code of the component BSON Value-Length Handler. The manipulation with an unknown input leads to a integer overflow vulnerability. The CWE definition for the vulnerability is CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. As an impact it is known to affect availability. CVE summarizes:

An integer overflow in BSON value-length handling in the MongoDB Go Driver can cause a runtime panic when an application validates or accesses a malformed BSON document. An unauthenticated actor who can supply BSON bytes to an affected application may terminate an unprotected application process, causing a denial of service. The driver's server-monitoring path contains panic recovery and is limited to server-selection failure.

The advisory is shared for download at jira.mongodb.org. This vulnerability was named CVE-2026-107324 since 10/07/2026. The exploitation appears to be easy. The attack can be initiated remotely.
