Technical details
The vulnerability is an uncontrolled recursion flaw (CWE-674) in Apache Thrift's Node.js bindings, affecting all versions before 0.23.0. An attacker can craft malicious Thrift protocol input that triggers recursive processing without proper depth limits, exhausting stack memory and causing the process to crash. This is a network-reachable vulnerability with no authentication required; any client capable of sending data to a Thrift service is a potential attacker. The impact is denial-of-service through application crash or hang. The fix is available in Apache Thrift version 0.23.0 and later.
