    Summary: XPath: Boolean expression infinite loop leads to denial of service via CPU exhaustion

    Details: Boolean expressions that evaluate to true can cause an infinite loop in logicalQuery.Select, leading to 100% CPU usage. This can be triggered by top-level selectors such as "1=1" or "true()".
