Description

The MongoDB Shell may be susceptible to control character injection where an attacker with control over the database cluster contents can inject control characters into the shell output. This may result in the display of falsified messages that appear to originate from mongosh or the underlying operating system, potentially misleading users into executing unsafe actions.

The vulnerability is exploitable only when mongosh is connected to a cluster that is partially or fully controlled by an attacker.

This issue affects mongosh versions prior to 2.3.9

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mongosh, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update mongosh to 2.3.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-1693 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
