Source description

As published by the source; long descriptions are shortened.

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.

# Patch Next advisory brief: CVE-2021-23631

Advisory: Path Traversal in convert-svg packages
IDs: CVE-2021-23631, GHSA-jv7g-9g6q-cxvw
Record: https://patchnext.com/advisories/cve-2021-23631 (revision 2, source checked 26 Oct 2026, 12:21 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm convert-svg-to-jpeg: affected <= 0.5.0
- npm convert-svg-core: affected <= 0.5.0
- npm convert-svg-to-png: affected <= 0.5.0

## Suggested inspection (read-only)
- `npm ls convert-svg-to-jpeg --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.
- `npm ls convert-svg-core --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.
- `npm ls convert-svg-to-png --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on convert-svg-to-jpeg, convert-svg-core, convert-svg-to-png.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
