A database user who can create and populate a suitably encoded collection can cause a later authorized directory restore to write those documents into a different collection that the user cannot modify directly. When both collection names resolve to the same destination, backed-up documents may be omitted; use of --drop can also replace the unintended destination collection. Exploitation requires an operator to restore the affected collection from a directory dump with write access to the destination. This issue affects MongoDB Database Tools versions 100.0.2 through versions before 100.20.1.","epss":{"date":"2026-11-04","percentile":0.05561,"score":0.00163},"exploits":[],"kev":null,"metrics":[{"score":2.1,"severity":"low","source":"CNA: mongodb","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:P/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},{"score":3.7,"severity":"low","source":"CNA: mongodb","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:N/I:L/A:L","version":"3.1"},{"score":2.1,"severity":"low","source":"NVD: cna@mongodb.com","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:P/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"},{"score":3.7,"severity":"low","source":"NVD: cna@mongodb.com","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:N/I:L/A:L","version":"3.1"}],"modifiedAt":1793736056300,"publishedAt":1793722896648,"references":[{"source":"CNA: mongodb","tags":[],"url":"https://github.com/mongodb/mongo-tools/blob/master/CHANGELOG.md"},{"source":"cna@mongodb.com","tags":[],"url":"https://github.com/mongodb/mongo-tools/blob/master/CHANGELOG.md"}],"remediation":[],"revision":"c7934b5fcacdc1d59b564443261d67c01af1517d58ddfa881e7b9cbc726c6600","sources":[{"modifiedAt":1793727524072,"name":"CNA: mongodb","retrievedAt":1793729365018,"url":"https://www.cve.org/CVERecord?id=CVE-2026-119674"},{"modifiedAt":1793736056300,"name":"NVD","retrievedAt":1793751685563,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-119674"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793858235406,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-119674"}],"ssvc":{"assessedAt":1793727512169,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"mongorestore may restore encoded collection names into an unintended collection","updatedAt":1793858235406}
