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.
Versions of the package spatie/browsershot before 5.0.2 are vulnerable to Directory Traversal due to URI normalisation in the browser where the file:// check can be bypassed with file:. An attacker could read any file on the server by exploiting the normalization of \ into /.
Versions of the package spatie/browsershot before 5.0.1 are vulnerable to Improper Input Validation due to improper URL validation through the setUrl method. An attacker can exploit this vulnerability by using leading whitespace (%20) before the file:// protocol, resulting in Local File Inclusion, which allows the attacker to read sensitive files on the server.
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 3.57.2 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.
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.
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.
