It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-21371 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- tenable-jira-cloud (PyPI): affected all versions; fixed in 1.1.21\n- tenable-jira-cloud (PyPI): affected all versions; fixed in 1.1.21\n- tenable-jira-cloud (PyPI): affected all versions; fixed in 1.1.22\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-2021-21371/ (Markdown: https://insights.sbomify.com/CVE-2021-21371/index.md)","id":"CVE-2021-21371","markdown":"https://insights.sbomify.com/CVE-2021-21371/index.md","name":"CVE-2021-21371","record":{"aliases":["GHSA-8278-88vv-x98r","PYSEC-2021-60"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Python Jira integration","requires_auth":"none","summary":"An attacker with local access can execute arbitrary code via a crafted YAML configuration file due to unsafe deserialization in the Tenable Jira Cloud integration.","user_interaction":"required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"jira_cloud","vendor":"tenable"}],"cvss":{"score":5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Tenable for Jira Cloud is an open source project designed to pull Tenable.io vulnerability data, then generate Jira Tasks and sub-tasks based on the vulnerabilities' current state.
