Details

A flaw was found in the github.com/antchfx/xpath component. A remote attacker could exploit this vulnerability by submitting crafted Boolean XPath expressions that evaluate to true. This can cause an infinite loop in the logicalQuery.Select function, leading to 100% CPU utilization and a Denial of Service (DoS) condition for the affected system.
