Summary
vantage6-server node accepts non-whitelisted algorithms from malicious server
Workarounds
None
Impact
A node does not check if an image is allowed to run if a parent_id is set. A malicious party that breaches the server may modify it to set a fake parent_id and send a task of a non-whitelisted algorithm. The node will then execute it because the parent_id that is set prevents checks from being run. Relevant node code here

CVE-2023-47631 has a CVSS score of 7.2 (High). The vector is network-reachable, high 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 (4.1.2); 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-2023-47631? CVE-2023-47631 is a high-severity security vulnerability in vantage6-server (pip), affecting versions < 4.1.2. It is fixed in 4.1.2.
- How severe is CVE-2023-47631? CVE-2023-47631 has a CVSS score of 7.2 (High). 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 packages are affected by CVE-2023-47631?
vantage6-server(pip) (versions < 4.1.2)vantage6-node(pip) (versions < 4.1.2)
- Is there a fix for CVE-2023-47631? Yes. CVE-2023-47631 is fixed in 4.1.2. Upgrade to this version or later.
- Is CVE-2023-47631 exploitable, and should I be worried? Whether CVE-2023-47631 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-2023-47631 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.
