An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-82355 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- apache-airflow (PyPI): affected all versions up to 3.3.0; no fix listed\n- airflow (Bitnami): affected from 3.3.0; fixed in 3.3.2\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-2026-82355/ (Markdown: https://insights.sbomify.com/CVE-2026-82355/index.md)","id":"CVE-2026-82355","markdown":"https://insights.sbomify.com/CVE-2026-82355/index.md","name":"CVE-2026-82355","record":{"aliases":["BIT-airflow-2026-82355","GHSA-9x6g-jfj6-r3jg","PYSEC-2026-3989"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Airflow","requires_auth":"none","summary":"Attackers can hijack sessions by forcing cookie precedence over bearer tokens, causing identity confusion and audit log misattribution in Apache Airflow.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"airflow","vendor":"apache"}],"cvss":{"score":4.2,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-384","name":"Session Fixation"}],"description":"When a request to the Airflow core API carries both a session cookie and an explicit `Authorization: Bearer` token, Airflow resolves the caller from the cookie and ignores the bearer token, inverting the intended precedence of bearer over cookie. The request then executes -- and is recorded in the audit log -- as the cookie's principal rather than the identity the client explicitly presented.\n\nOnly Apache Airflow 3.3.0 and 3.3.1 are affected. Earlier releases do not contain the code path that caches the cookie-derived user, and are not vulnerable.\n\nExploiting this requires an attacker to first place a valid session cookie of their own into the victim's browser or client: for example by cookie tossing from a sibling subdomain, through cross-site scripting in a separate application sharing a parent domain, or via a shared workstation. Deployments that host the Airflow UI on a domain shared with other applications are therefore the most exposed; a deployment on a dedicated domain with no co-hosted applications is not reachable this way. The consequence is principal confusion and misattributed audit records rather than a direct privilege escalation.\n\nUsers of 3.3.0 or 3.3.1 should upgrade to Apache Airflow 3.3.2 or later, which resolves the caller from the explicitly supplied credential whenever one is present.","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: Session cookie silently overrides explicit Authorization bearer header, enabling session fixation","id":"CVE-2026-82355","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"apache:airflow","products":["apache:airflow"],"type":"auth_bypass","year":"2026"},"n_packages":2,"n_references":3,"next":{"headline":"Imprivata EAM: Unrotatable X.509 RSA Key Pair in Production","id":"CVE-2026-82356"},"packages":[{"ecosystem":"Bitnami","fixed":["3.3.2"],"introduced":["3.3.0"],"last_affected":[],"package":"airflow","purl":"pkg:bitnami/airflow","source":"BIT-airflow-2026-82355"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["3.3.0","3.3.1"],"package":"apache-airflow","purl":"pkg:pypi/apache-airflow","source":"PYSEC-2026-3989"}],"prev":{"headline":"Apache Roller: Cross-weblog resource tampering via unscoped authoring lookups","id":"CVE-2026-82348"},"products":["Apache Airflow"],"published":"2026-09-21","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":"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":"partial"},"state":"PUBLISHED","updated":"2026-09-21","vendors":["Apache Software Foundation"]},"summary":"Attackers can hijack sessions by forcing cookie precedence over bearer tokens, causing identity confusion and audit log misattribution in Apache Airflow.","url":"https://insights.sbomify.com/CVE-2026-82355/"}
