{"id":"BIT-mongodb-2026-84967","summary":"Arbitrary command execution via shell-expanded connection string in Launch MongoDB Shell terminal","details":"A component of the MongoDB extension for Visual Studio Code does not neutralize special characters in a connection string before that value is placed into a command line the extension composes for an integrated terminal. An unauthenticated remote unauthorized-user who persuades a developer to accept a user-supplied connection target, and then to open the extension's shell feature, can place characters of the unauthorized-user’s choosing into that command line. No privileges on the developer's machine are required, but several user actions are. The confirmation the developer sees does not display the supplied text.","aliases":["CVE-2026-84967"],"modified":"2026-09-10T09:30:05.470126115Z","published":"2026-09-10T08:59:52.945Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:mongodb:mongodb:*:*:*:*:*:visual_studio_code:*:*"]},"references":[{"type":"REPORT","url":"https://jira.mongodb.org/browse/VSCODE-798"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-84967"}],"affected":[{"package":{"name":"mongodb","ecosystem":"Bitnami","purl":"pkg:bitnami/mongodb"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.13.0"},{"fixed":"1.17.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/mongodb/BIT-mongodb-2026-84967.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/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"}]}],"schema_version":"1.9.0"}
