Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Spatie/browsershot, 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

Browsershot version 3.57.2 allows an external attacker to remotely obtain arbitrary local files. This is possible because the application does not validate that the HTML content passed to the Browsershot::html method does not contain URL's that use the file:// protocol.
