CVE-2026-42333
Quarkus OpenAPI Generator is Quarkus' extensions for generation of Rest Clients and server stubs generation.
Does this matter?
Lower severity and a low EPSS score (0.40%). Track it; it rarely justifies an emergency change on its own.
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.
