Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-67587 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-2026-67587/ (Markdown: https://insights.sbomify.com/CVE-2026-67587/index.md)","id":"CVE-2026-67587","markdown":"https://insights.sbomify.com/CVE-2026-67587/index.md","name":"CVE-2026-67587","record":{"aliases":["BIT-airflow-2026-67587","GHSA-2qjv-p2gc-mjg2","MINI-j8jm-4p84-qvfx","PYSEC-2026-3708"],"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 Apache Airflow Scheduler by exploiting a deserialization gadget in the Task SDK.","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 Task SDK rebuilt a `Callback` object from serialized data by re-running its constructor, which imports the module named by the stored callback path. Because `SyncCallback` is itself an Airflow class it passes the default `allowed_deserialization_classes` allow-list, so tightening that setting does not help. A Dag author — who controls a task instance's `next_kwargs` through the task execution API — can therefore cause an arbitrary module to be imported inside the scheduler process, when the scheduler's `awaiting_input` timeout sweep deserializes that value. No non-default configuration is required; the sweep runs unconditionally. Versions before 3.3.0 are not affected: the class existed, but the scheduler sweep that reaches it did not. This is a separate code path from CVE-2026-58076 and CVE-2026-67260, which cover different gadgets reaching deserialization — applying either of those fixes does not address this one. Users are advised to upgrade to apache-airflow 3.3.1 or later.","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: DAG-author remote code execution on the Scheduler via a Serde `Callback` deserialization gadget","id":"CVE-2026-67587","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"apache:airflow","products":["apache:airflow"],"type":"deserialization","year":"2026"},"n_packages":4,"n_references":4,"next":{"headline":"Apache Qpid ProtonJ2: Unbounded symbol value caching can lead to pre-authentication resource exhaustion","id":"CVE-2026-67588"},"packages":[{"ecosystem":"Bitnami","fixed":["3.3.1"],"introduced":["3.3.0"],"last_affected":[],"package":"airflow","purl":"pkg:bitnami/airflow","source":"BIT-airflow-2026-67587"},{"ecosystem":"PyPI","fixed":["3.3.1"],"introduced":["3.3.0"],"last_affected":[],"package":"apache-airflow","purl":null,"source":"GHSA-2qjv-p2gc-mjg2"},{"ecosystem":"PyPI","fixed":["3.3.1"],"introduced":["3.3.0"],"last_affected":[],"package":"apache-airflow","purl":"pkg:pypi/apache-airflow","source":"GHSA-2qjv-p2gc-mjg2"},{"ecosystem":"PyPI","fixed":["3.3.1"],"introduced":["3.3.0"],"last_affected":[],"package":"apache-airflow","purl":"pkg:pypi/apache-airflow","source":"PYSEC-2026-3708"}],"prev":{"headline":"Atom Exhaustion via _entities Representation Keys in DivvyPayHQ absinthe_federation","id":"CVE-2026-67585"},"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 Apache Airflow Scheduler by exploiting a deserialization gadget in the Task SDK.","url":"https://insights.sbomify.com/CVE-2026-67587/"}
