Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Quarkus-openapi-generator versions before 2.16.0 are affected by a Zip Slip path traversal in the unzip() method of ApicurioCodegenWrapper, which writes ZIP entries without checking that they stay inside the output directory. An attacker who can serve a crafted ZIP archive to the code generation step, such as through a controlled or intercepted Apicurio registry connection, could write arbitrary files on the build machine. Upgrade to version 2.16.0 or later.
