Remediation
Vendor solution
We do not expect to release a version that fixes this problem. Instead, we recommend users to migrate to one of the other actively maintained web service stacks such as Apache CXF (https://cxf.apache.org) or Apache Axis (https://axis.apache.org).
Apache SOAP is an archived project, with the last release published in 2003. This means it is no longer maintained, does not receive updates, and we do not commit to publishing CVE's for security problems in this project. This advisory is published purely as a courtesy.
