{"id":"UBUNTU-CVE-2026-119675","details":"MongoDB Database Tools mongorestore inconsistently handles the system.buckets. prefix when validating collection names in an untrusted dump. A specially crafted collection name can bypass special-collection guards and operator namespace filters, causing a restore to create an unauthorized user-chosen database account, including an account with the root role. Exploitation requires an operator to restore unauthorized user-controlled data using credentials with sufficient user-management privileges on the destination deployment. Excluding the admin namespace alone does not prevent this behavior. This issue affects MongoDB Database Tools versions 100.4.0 through versions before 100.20.1.","modified":"2026-11-05T11:47:25.546642642Z","published":"2026-11-03T17:18:00Z","upstream":["CVE-2026-119675"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-119675"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-119675"},{"type":"REPORT","url":"https://github.com/mongodb/mongo-tools/blob/master/CHANGELOG.md"}],"affected":[{"package":{"name":"mongo-tools","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/mongo-tools?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.2.11-1","3.2.11-1ubuntu1","3.4.14-1","3.4.14-2","3.6.3-0ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"mongo-tools","binary_version":"3.6.3-0ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119675.json"}},{"package":{"name":"mongo-tools","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/mongo-tools?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.6.3-0ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"mongo-tools","binary_version":"3.6.3-0ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119675.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:P/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H"},{"type":"Ubuntu","score":"medium"}]}
