CVE-2026-42333: CWE-200: Exposure of Sensitive Information to an Unauthorized Actor in quarkiverse quarkus-openapi-generator
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.
AI Analysis
Technical Summary
The quarkus-openapi-generator extension for Quarkus versions before 2.11.1-lts, 2.16.0-lts, and 2.17.0 contains a vulnerability where the generated authentication filter matches OpenAPI path templates too broadly. This causes a security scheme configured for one API operation to be applied to a different operation with the same HTTP method but a partially matching path. Consequently, authentication credentials such as bearer tokens, API keys, or basic credentials may be sent to unintended endpoints. The issue has been patched in the specified fixed versions.
Potential Impact
Unauthorized endpoints may receive sensitive authentication credentials due to overly broad matching of OpenAPI path templates. This exposure could lead to leakage of bearer tokens, API keys, or basic credentials to endpoints not intended to receive them. However, there are no reports of known exploits in the wild. The impact is limited to potential exposure of sensitive information within the affected versions of the quarkus-openapi-generator.
Mitigation Recommendations
This vulnerability has been patched in quarkus-openapi-generator versions 2.11.1-lts, 2.16.0-lts, and 2.17.0. Users should upgrade to one of these fixed versions to remediate the issue. Patch status is confirmed by the vendor advisory. No additional mitigation steps are indicated.
