Description

snowflake-connector-net is the Snowflake Connector for .NET. Snowflake discovered and remediated a vulnerability in the Snowflake Connector for .NET in which files downloaded from stages are temporarily placed in a world-readable local directory, making them accessible to unauthorized users on the same machine. This vulnerability affects versions 2.0.12 through 4.2.0 on Linux and macOS. Snowflake fixed the issue in version 4.3.0.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Snowflake.Data. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update Snowflake.Data to 4.3.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-24788 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.

  4. How O3 protects you

    O3 pinpoints whether CVE-2025-24788 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to CVE-2025-24788. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
