CVE Severity Published▾ Status Exploitation Description
CVE-2026-42333 Medium 2026-05-09 No exploit published Proof of concept only 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.
CVE-2026-40180 High 2026-04-10 Protected by Waratek Proof of concept only Quarkus OpenAPI Generator is Quarkus' extensions for generation of Rest Clients and server stubs generation. Prior to 2.16.0 and 2.15.0-lts, the unzip() method in ApicurioCodegenWrapper.java extracts ZIP entries without validating that the resolved file path stays within the intended output directory. At line 101, the destination is constructed as new File(toOutputDir, entry.getName()) and the content is written immediately. A malicious ZIP archive containing entries with path traversal sequences (e.g., ../../malicious.java) would write files outside the target directory. This vulnerability is fixed in 2.16.0 and 2.15.0-lts.
CVE-2024-35219 High 2024-05-27 Protected by Waratek Exploited OpenAPI Generator allows generation of API client libraries (SDK generation), server stubs, documentation and configuration automatically given an OpenAPI Spec. Prior to version 7.6.0, attackers can exploit a path traversal vulnerability to read and delete files and folders from an arbitrary, writable directory as anyone can set the output folder when submitting the request via the `outputFolder` option. The issue was fixed in version 7.6.0 by removing the usage of the `outputFolder` option. No known workarounds are available.
CVE-2023-27162 Critical 2023-03-31 No exploit published Proof of concept only openapi-generator up to v6.4.0 was discovered to contain a Server-Side Request Forgery (SSRF) via the component /api/gen/clients/{language}. This vulnerability allows attackers to access network resources and sensitive information via a crafted API request.
CVE-2021-21430 Medium 2021-05-10 No exploit published No public exploit OpenAPI Generator allows generation of API client libraries (SDK generation), server stubs, documentation and configuration automatically given an OpenAPI Spec. Using `File.createTempFile` in JDK will result in creating and using insecure temporary files that can leave application and system data vulnerable to attacks. Auto-generated code (Java, Scala) that deals with uploading or downloading binary data through API endpoints will create insecure temporary files during the process. Affected generators: `java` (jersey2, okhttp-gson (default library)), `scala-finch`. The issue has been patched with `Files.createTempFile` and released in the v5.1.0 stable version.
CVE-2021-21428 Critical 2021-05-10 No exploit published No public exploit Openapi generator is a java tool which allows generation of API client libraries (SDK generation), server stubs, documentation and configuration automatically given an OpenAPI Spec. openapi-generator-online creates insecure temporary folders with File.createTempFile during the code generation process. The insecure temporary folders store the auto-generated files which can be read and appended to by any users on the system. The issue has been patched with `Files.createTempFile` and released in the v5.1.0 stable version.
CVE-2021-21429 Medium 2021-04-27 No exploit published No public exploit OpenAPI Generator allows generation of API client libraries, server stubs, documentation and configuration automatically given an OpenAPI Spec. Using `File.createTempFile` in JDK will result in creating and using insecure temporary files that can leave application and system data vulnerable to attacks. OpenAPI Generator maven plug-in creates insecure temporary files during the process. The issue has been patched with `Files.createTempFile` and released in the v5.1.0 stable version.
CVE-2019-11405 High 2019-04-22 No exploit published No public exploit OpenAPI Tools OpenAPI Generator before 4.0.0-20190419.052012-560 uses http:// URLs in various build.gradle, build.gradle.mustache, and build.sbt files, which may have caused insecurely resolved dependencies.
