CVE-2026-120822
Missing Authorization Check in MongoDB Server Replication-Related Administrative Command Leads to Unauthorized Data Access
MongoDB Server may omit an authorization check on the resource that a replication-related administrative command actually targets, because that check is conditioned on a value taken from the client's own request. A user holding backup and restore privileges may therefore read and relocate collections outside the set that user is permitted to access. This may result in unintended access to data and unintended changes to the collection catalog.
