The privilege evaluation performed while a view definition is validated does not cover a nested portion of the supplied pipeline, so the resulting view returns data the user is otherwise refused. This may result in unintended access to data, including stored authentication material.","epss":{"date":"2026-11-13","percentile":0.38559,"score":0.00438},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://jira.mongodb.org/browse/SERVER-136876"}],"kev":null,"metrics":[{"score":7.1,"severity":"high","source":"CNA: mongodb","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},{"score":6.5,"severity":"medium","source":"CNA: mongodb","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},{"score":7.1,"severity":"high","source":"NVD: cna@mongodb.com","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/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":6.5,"severity":"medium","source":"NVD: cna@mongodb.com","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"}],"modifiedAt":1794601959390,"publishedAt":1794342080207,"references":[{"source":"CNA: mongodb","tags":[],"url":"https://jira.mongodb.org/browse/SERVER-136876"},{"source":"CNA: mongodb","tags":[],"url":"https://jira.mongodb.org/browse/SERVER-136878"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://jira.mongodb.org/browse/SERVER-136876"},{"source":"cna@mongodb.com","tags":[],"url":"https://jira.mongodb.org/browse/SERVER-136876"},{"source":"cna@mongodb.com","tags":[],"url":"https://jira.mongodb.org/browse/SERVER-136878"}],"remediation":[],"revision":"2dc8fad6286e38fed27f1c0fac0e5e5d98685d0232a7dd9c152e3644f3b2b6af","sources":[{"modifiedAt":1794601959390,"name":"CNA: mongodb","retrievedAt":1794604141734,"url":"https://www.cve.org/CVERecord?id=CVE-2026-120825"},{"modifiedAt":1794348539707,"name":"NVD","retrievedAt":1794357161524,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-120825"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1794604159721,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-120825"}],"ssvc":{"assessedAt":1794601950370,"automatable":"no","exploitation":"poc","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Improper Authorization in MongoDB Server Aggregation Framework View Definition Validation Leads to Unauthorized Collection Access","updatedAt":1794604159721}
