How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-4914, inspect your project dependencies for Cecil/cecil:

inspect dependencies for cecil/cecil

Analyze the terminal output to locate any version of Cecil/cecil in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 7.47.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-23: Relative Path Traversal, where the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. In Cecil/cecil, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Relative Path Traversal in GitHub repository cecilapp/cecil prior to 7.47.1.
