**Name of the Vulnerable Software and Affected Versions**
The product name cannot be determined (affected versions not specified)
**Description**
The SOAP XML parser contains a flaw where the `cleanup xml node()` function recurses once per XML nesting level without a depth limit. An unauthenticated attacker can send a SOAP request with tens of thousands of nested elements to any SoapServer endpoint, leading to stack exhaustion and a process crash. This unbounded recursion also affects the SOAP value decoder and the WSDL node search helper.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
