Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The quarkus-openapi-generator package, versions before 2.16.0-lts and from 2.16.0 up to 2.17.0, has overly broad path-template matching in its generated authentication filter. A client request whose path only partly resembles a protected operation can receive that operation's credentials, so bearer tokens, API keys, or basic credentials may be sent to unintended endpoints by ordinary generated-client use, with no special access needed. Upgrade to 2.16.0-lts or 2.17.0.
