Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

Browsershot version 3.57.3 allows an external attacker to remotely obtain arbitrary local files. This is possible because the application does not validate that the JS content imported from an external source passed to the Browsershot::html method does not contain URLs that use the file:// protocol.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for spatie/browsershot, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update spatie/browsershot to 3.57.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-43984 is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
