CVE-2026-14881

Arbitrary command execution via imported OIDC browser command

Published Jul 22, 2026 · Updated Jul 22, 2026

OS command injection in MongoDB Compass 1.38.0 through 1.49.6 allows attackers to execute arbitrary commands through imported connections. The connection importer accepts a browser-open command from serialized connection options without enforcing the settings-only restriction, and the OIDC authentication flow passes that value to the operating system. Execution requires a user to import the crafted connection and initiate an OIDC-authenticated cluster connection; commands run with that user's privileges.
