Versions of the package spatie/browsershot before 5.0.5 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.

Versions of the package spatie/browsershot from 0.0.0 are vulnerable to Server-side Request Forgery (SSRF) in the setUrl() function due to a missing restriction on user input, enabling attackers to access localhost and list all of its directories.

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.

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.

Browsershot version 3.57.2 allows an external attacker to remotely obtain arbitrary local files. This is possible because the application does not validate the URL protocol passed to the Browsershot::url method.

Versions of the package spatie/browsershot before 5.0.5 are vulnerable to Improper Input Validation due to improper URL validation through the setUrl method, which results in a Local File Inclusion allowing the attacker to read sensitive files.

Note:

This is a bypass of the fix for CVE-2024-21549.

This affects the package spatie/browsershot from 0.0.0. By specifying a URL in the file:// protocol an attacker is able to include arbitrary files in the resultant PDF.
