CVE-2026-4645 Details
Description
Rejected reason: Duplicate of CVE-2026-32287
A denial-of-service vulnerability has been identified in the Antchfx XPath component, specifically in version 1.3.5. The issue arises when a remote attacker submits crafted Boolean XPath expressions that evaluate to true. This exploitation causes the 'logicalQuery.Select' function to enter an infinite loop, resulting in 100% CPU utilization and creating a DoS condition on the affected system. The vulnerability is present in applications that accept user-controlled XPath expressions and pass them to query functions, such as 'QuerySelectorAll', in the downstream Antchfx query packages.
Users can upgrade to Antchfx XPath version 1.3.6, which addresses this vulnerability by modifying the 'logicalQuery.Select' function to include a termination condition that prevents the infinite loop.
