Recommendation: Monitor — no exploitation signal at the moment.

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 /.
