Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-58076 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- apache-airflow (PyPI): affected from 3.3.0; fixed in 3.3.1\n- apache-airflow (PyPI): affected from 3.3.0; fixed in 3.3.1\n- apache-airflow (PyPI): affected from 3.3.0; fixed in 3.3.1\n- airflow (Bitnami): affected from 3.3.0; fixed in 3.3.1\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-2026-58076/ (Markdown: https://insights.sbomify.com/CVE-2026-58076/index.md)","id":"CVE-2026-58076","markdown":"https://insights.sbomify.com/CVE-2026-58076/index.md","name":"CVE-2026-58076","record":{"aliases":["BIT-airflow-2026-58076","GHSA-8prw-8m6x-8w6f","MINI-92m7-f8j7-mm39","PYSEC-2026-3991"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Airflow","requires_auth":"low_privilege","summary":"A DAG author can achieve remote code execution on the Scheduler or API server by exploiting unguarded import_string calls during exception deserialization.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"airflow","vendor":"apache"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Apache Airflow's serialization layer reconstructed exception nodes by calling `import_string()` on a class name taken from the serialized blob and instantiating it with arguments from the same blob, with no restriction on what could be imported. An operator's `executor_config` reaches that branch, so a Dag author could place a value there that causes an arbitrary callable to be imported and invoked -- for example `subprocess.check_output`, or `builtins.eval` on the `builtins`-prefixed variant. The code runs in the **Scheduler**, which reconstructs serialized Dags in its normal loop with no request involved, and in the **API server**, on any authenticated read of the Dag such as `GET /api/v2/dags/{dag_id}/details`. Both are components the Airflow security model states must never execute Dag-author code, and both hold the metadata database credentials and the JWT signing secret. No non-default configuration is required. This is a **different sink from CVE-2026-33264**, which covered only the trigger branch of the same deserializer: deployments that upgraded in response to that advisory are still affected through the exception branch and must upgrade again. Users are advised to upgrade to apache-airflow 3.3.1 or later, which restricts the imported class to a subclass of `BaseException`.","ecosystems":["Bitnami","PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Apache Airflow exception-node deserialization permits arbitrary callable execution","id":"CVE-2026-58076","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"apache:airflow","products":["apache:airflow"],"type":"deserialization","year":"2026"},"n_packages":4,"n_references":3,"next":{"headline":"Joomla Extension - weeblr.com - Unauthenticated stored XSS in 4Analytics \u003c 5.0.2","id":"CVE-2026-58077"},"packages":[{"ecosystem":"Bitnami","fixed":["3.3.1"],"introduced":["3.3.0"],"last_affected":[],"package":"airflow","purl":"pkg:bitnami/airflow","source":"BIT-airflow-2026-58076"},{"ecosystem":"PyPI","fixed":["3.3.1"],"introduced":["3.3.0"],"last_affected":[],"package":"apache-airflow","purl":null,"source":"GHSA-8prw-8m6x-8w6f"},{"ecosystem":"PyPI","fixed":["3.3.1"],"introduced":["3.3.0"],"last_affected":[],"package":"apache-airflow","purl":"pkg:pypi/apache-airflow","source":"GHSA-8prw-8m6x-8w6f"},{"ecosystem":"PyPI","fixed":["3.3.1"],"introduced":["3.3.0"],"last_affected":[],"package":"apache-airflow","purl":"pkg:pypi/apache-airflow","source":"PYSEC-2026-3991"}],"prev":{"headline":"Path traversal in ONE","id":"CVE-2026-58075"},"products":["Apache Airflow"],"published":"2026-08-12","related":[{"cvss_score":9.8,"headline":"Apache Airflow's Experimental API Authentication Bypass","id":"CVE-2020-13927","kev_date_added":"2022-01-18","published":"2020-11-10"},{"cvss_score":8.8,"headline":"Apache Airflow Command Injection","id":"CVE-2020-11978","kev_date_added":"2022-01-18","published":"2020-07-16"},{"cvss_score":9.8,"headline":"Apache Airflow: DAG author RCE on webserver via unrestricted import_string() in BaseSerialization.deserialize()","id":"CVE-2026-33264","kev_date_added":null,"published":"2026-07-07"},{"cvss_score":9.8,"headline":"Apache Airflow: Privilege escalation using airflow logs","id":"CVE-2023-25754","kev_date_added":null,"published":"2023-05-08"},{"cvss_score":9.8,"headline":"Apache Airflow, Apache Airflow MySQL Provider: Arbitrary file read via MySQL provider in Apache Airflow","id":"CVE-2023-22884","kev_date_added":null,"published":"2023-01-21"},{"cvss_score":9.8,"headline":"Apache Airflow Pinot provider allowed Command Injection","id":"CVE-2022-38649","kev_date_added":null,"published":"2022-11-22"},{"cvss_score":9.8,"headline":"Apache Airlfow Pig Provider RCE","id":"CVE-2022-40189","kev_date_added":null,"published":"2022-11-22"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-16","vendors":["Apache Software Foundation"]},"summary":"A DAG author can achieve remote code execution on the Scheduler or API server by exploiting unguarded import_string calls during exception deserialization.","url":"https://insights.sbomify.com/CVE-2026-58076/"}
