Overview
Affected versions of this package are vulnerable to Missing Release of File Descriptor or Handle after Effective Lifetime via the ParseFile function. An attacker can cause the process to exhaust available file descriptors and disrupt service by repeatedly triggering schema parsing operations, leading to resource exhaustion and potential denial of service.
Note:
This is only exploitable if the application exposes repeated schema parsing to an attacker-controlled path.
