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()".

Severity
7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
