Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-125: Out-of-bounds Read, where the product reads data past the end, or before the beginning, of the intended buffer. 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

Versions of the package spatie/browsershot before 5.0.3 are vulnerable to Improper Input Validation due to improper URL validation through the setUrl method. An attacker can exploit this vulnerability by utilizing view-source:file://, which allows for arbitrary file reading on a local file. **Note:** This is a bypass of the fix for [CVE-2024-21544](https://security.snyk.io/vuln/SNYK-PHP-SPATIEBROWSERSHOT-8496745).
