It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-21429 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.openapitools:openapi-generator-maven-plugin (Maven): affected all versions; fixed in 5.1.0\n- org.openapitools:openapi-generator-maven-plugin (Maven): affected all versions; fixed in 5.1.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2021-21429/ (Markdown: https://insights.sbomify.com/CVE-2021-21429/index.md)","id":"CVE-2021-21429","markdown":"https://insights.sbomify.com/CVE-2021-21429/index.md","name":"CVE-2021-21429","record":{"aliases":["GHSA-867q-77cc-98mv"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenAPI Generator Maven plugin","requires_auth":"none","summary":"Attackers can read or modify insecure temporary files created by the OpenAPI Generator Maven plugin, potentially exposing sensitive data or altering code generation.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"openapi_generator","vendor":"openapi-generator"}],"cvss":{"score":4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-552","name":"Files or Directories Accessible to External Parties"}],"description":"OpenAPI Generator allows generation of API client libraries, server stubs, documentation and configuration automatically given an OpenAPI Spec.
