An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-50943 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- apache-airflow (PyPI): affected all versions; fixed in 2.8.1\n- apache-airflow (PyPI): affected all versions; fixed in 2.8.1rc1\n- apache-airflow (PyPI): affected all versions; fixed in 2.8.1rc1\n- airflow (Bitnami): affected all versions; fixed in 2.8.1\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-2023-50943/ (Markdown: https://insights.sbomify.com/CVE-2023-50943/index.md)","id":"CVE-2023-50943","markdown":"https://insights.sbomify.com/CVE-2023-50943/index.md","name":"CVE-2023-50943","record":{"aliases":["BIT-airflow-2023-50943","ECHO-55b0-7d4f-b496","GHSA-c3c6-f2ww-xfr2","PYSEC-2024-13"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Airflow","requires_auth":"none","summary":"An attacker with DAG author privileges can bypass pickling protections to execute arbitrary code via poisoned XCom data in Apache Airflow.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"airflow","vendor":"apache"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Apache Airflow, versions before 2.8.1, have a vulnerability that allows a potential attacker to poison the XCom data by bypassing the protection of \"enable_xcom_pickling=False\" configuration setting resulting in poisoned data after XCom deserialization.
