npm ls office-converter

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

Note: The npm ls office-converter command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Office converter, 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

All versions of `office-converter` are vulnerable to Remote Code Execution. Due to insufficient input validation an attacker could run arbitrary commands on the server thus rendering the package vulnerable to Remote Code Execution. ## Recommendation No fix is currently available. Consider using an alternative module until a fix is made available.
