CVE-2025-1022 (opens in a new tab)How to fix?
Upgrade spatie/browsershot to version 5.0.5 or higher.
Overview
spatie/browsershot is a library for converting a webpage to an image or pdf using headless Chrome.
Affected versions of this package are vulnerable to Improper Input Validation in the setHtml function, invoked by Browsershot::html(), which can be bypassed by omitting the slashes in the file URI (e.g., file:../../../../etc/passwd). This is due to missing validations of the user input that should be blocking file URI schemes (e.g., file:// and file:/) in the HTML content.
Note: Further analysis has identified additional proof-of-concept exploits leveraging the vulnerable function. Developers using this package should ensure proper input validation to mitigate potential risks, as the issue remains unaddressed.
