Summary
snowflake-sdk may incorrectly validate temporary credential cache file permissions
Issue
Snowflake discovered and remediated a vulnerability in the Snowflake NodeJS Driver. File permissions checks of the temporary credential cache could be bypassed by an attacker with write access to the local cache directory.
This vulnerability affects versions 1.12.0 through 2.0.1 on Linux. Snowflake fixed the issue in version 2.0.2.
Vulnerability Details
On Linux, when either EXTERNALBROWSER or USERNAME_PASSWORD_MFA authentication methods are used with temporary credential caching enabled, the Snowflake NodeJS Driver will cache temporary credentials in a local file. Due to a bug, the check verifying that the cache file can be accessed only by the user running the Driver always succeeded, but didn’t verify the permissions or the ownership correctly. An attacker with write access to the local cache folder could plant an empty file there and the Driver would use it to store temporary credentials instead of rejecting it due to overly broad permissions.

Impact
CVE-2025-24791 has a CVSS score of 4.4 (Medium). The vector is requires local access, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2.0.2); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2025-24791? CVE-2025-24791 is a medium-severity security vulnerability in snowflake-sdk (npm), affecting versions >= 1.12.0, <= 2.0.1. It is fixed in 2.0.2.
- How severe is CVE-2025-24791? CVE-2025-24791 has a CVSS score of 4.4 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of snowflake-sdk are affected by CVE-2025-24791? snowflake-sdk (npm) versions >= 1.12.0, <= 2.0.1 is affected.
- Is there a fix for CVE-2025-24791? Yes. CVE-2025-24791 is fixed in 2.0.2. Upgrade to this version or later.
- Is CVE-2025-24791 exploitable, and should I be worried? Whether CVE-2025-24791 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-24791 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
