Backport
This PR is auto-generated from #14501 to be assessed for backporting due to the inclusion of the label backport/1.8.x.
The below text is copied from the body of the original PR.
A panic can be caused if input to the
ParsePolicyfunction contains a field whose value is an empty slice. This is due to a lack of length check in the underlyinggetRuleInfofunction which assumes the parsed slice to contain at least one value. The panic can be prevented by returning an error fromgetRuleInfoif an empty slice is encountered.
