How to Fix CVE-2021-23631

To remediate this vulnerability, upgrade all affected Convert svg core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

convert-svg-core fixed: Latest secure release 
npm install convert-svg-core@Latest secure release
convert-svg-to-png fixed: Latest secure release 
npm install convert-svg-to-png@Latest secure release
convert-svg-to-jpeg fixed: Latest secure release 
npm install convert-svg-to-jpeg@Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls convert-svg-core

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2021-23631, inspect your project dependencies using npm:

npm ls convert-svg-core

Analyze the terminal output to locate any version of Convert svg core 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 convert-svg-core 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Convert svg core, 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

This affects all versions of package convert-svg-core; all versions of package convert-svg-to-png; all versions of package convert-svg-to-jpeg. Using a specially crafted SVG file, an attacker could read arbitrary files from the file system and then show the file content as a converted PNG file.
