How to Check if You Are Affected

To determine whether your application is affected by GHSA-q95h-cqrv-8jv5, inspect your project dependencies for Exiftool vendored:

inspect dependencies for exiftool_vendored

Analyze the terminal output to locate any version of Exiftool vendored in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 12.25.0), 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-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In Exiftool vendored, 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.
