Summary
Vulnerability in Quarkus OpenAPI Generator before versions 2.11.1-lts, 2.16.0-lts, and 2.17.0, where the generated authentication filter matches OpenAPI path templates too broadly. This causes bearer tokens, API keys, or credentials to be sent to unintended endpoints.
Risk Assessment
An attacker can intercept credentials sent to the wrong endpoint, potentially leading to leakage of sensitive information.
Recommendation
Update Quarkus OpenAPI Generator to version 2.11.1-lts, 2.16.0-lts, or 2.17.0.
Original NVD description (English source)
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.
