For how to report a security problem, see the ASF security process. Apache CXF's existing security advisories are published at https://cxf.apache.org/security-advisories.html. Please do not open public GitHub issues or pull requests for security reports.
apache/cxf-build-utils is shared build utilities for the Apache CXF project. It runs at build time and is not a runtime service, so it has no runtime threat
model of its own; its security context is covered by the Apache CXF umbrella threat model, which places
build-time tooling outside the runtime model:
