MEDIUMCVSS 6.7/10EPSS 0.34%

Last modified

CVE-2026-120822 is a medium-severity vulnerability rated 6.7/10 on the CVSS scale. 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. EPSS estimates a 0.34% chance of exploitation in the next 30 days.

Description

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.
