Description

A SMB force-authentication vulnerability exists in all versions of OPA for Windows prior to v0.68.0. The vulnerability exists because of improper input validation, allowing a user to pass an arbitrary SMB share instead of a Rego file as an argument to OPA CLI or to one of the OPA Go library’s functions.
