Upgrade to quarkus-openapi-generator versions 2.11.1-lts, 2.16.0-lts, or 2.17.0 or later, where this issue has been patched. Patch status is confirmed by the vendor's versioning information. No other mitigation steps are indicated.
Description
Quarkus OpenAPI Generator is Quarkus' extensions for generation of Rest Clients and server stubs generation. Prior to versions 2.11.1-lts, 2.16.0-lts, and 2.17.0, the generated authentication filter matches OpenAPI path templates too broadly when deciding whether to attach credentials. A security scheme configured for one operation can therefore be applied to a different same-method operation whose path only partially resembles the protected template, causing bearer tokens, API keys, or basic credentials to be sent to unintended endpoints. This issue has been patched in versions 2.11.1-lts, 2.16.0-lts, and 2.17.0.
