Information Disclosure in io.quarkiverse.openapi.generator:quarkus-openapi-generator (CVE-2026-42333)
Summary
Vulnerability in io.quarkiverse.openapi.generator:quarkus-openapi-generator (CVE-2026-42333). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 2.17.0 or later.
Original description
The description as published by the 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.
