CVE-2026-82057

Name of the Vulnerable Software and Affected Versions MongoDB (affected versions not specified)

Description An authenticated user with readWrite privileges can crash the mongod server process. This occurs when a custom WiredTiger storage configuration option is specified with an incompatible value during collection creation, leading to type confusion in the storage engine layer. When documents are read from the misconfigured collection, a mismatch in the expected data format causes corrupted memory interpretation and a server crash. This configuration persists across restarts, necessitating manual operator intervention for remediation.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
