Istio before 1.8.6 and 1.9.x before 1.9.5 has a remotely exploitable vulnerability where an HTTP request path with multiple slashes or escaped slash characters (%2F or %5C) could potentially bypass an Istio authorization policy when path based authorization rules are used.
Weakness
The product uses a name or reference to access a resource, but the name/reference resolves to a resource that is outside of the intended control sphere.
