Lifecycle Timeline
2DescriptionCVE.org
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.
AnalysisAI
Command injection in the MongoDB extension for Visual Studio Code allows a remote attacker, via social engineering, to inject arbitrary shell characters into a terminal command composed by the extension when a developer opens its integrated shell feature against an attacker-controlled connection target. The extension fails to neutralize special characters from user-supplied MongoDB connection strings before embedding them in the command line, and the confirmation dialog shown to the developer does not render the injected payload, preventing visual detection. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires two sequential developer actions: (1) the developer must accept a user-supplied MongoDB connection target (URI) into the extension - this could be provided via a shared README, a third-party database invitation, a misconfigured environment variable, or direct social engineering; and (2) the developer must subsequently open the extension's integrated shell feature (which launches mongosh in the VS Code terminal) against that connection. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-provided CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:N) rates this at 5.1, attributing only low integrity impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patched version has been independently confirmed at time of analysis - the only reference is the internal Jira ticket VSCODE-798. … Detailed patch versions, workarounds, and compensating controls in full report. |
