Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-17526 exists.\n\nAffected packages and fixed versions:\n- apache-airflow (PyPI): affected all versions; fixed in 1.10.14\n- apache-airflow (PyPI): affected all versions; fixed in 1.10.14\n- apache-airflow (PyPI): affected all versions; fixed in 1.10.14\n- airflow (Bitnami): affected all versions; fixed in 1.10.14\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-2020-17526/ (Markdown: https://insights.sbomify.com/CVE-2020-17526/index.md)","id":"CVE-2020-17526","markdown":"https://insights.sbomify.com/CVE-2020-17526/index.md","name":"CVE-2020-17526","record":{"aliases":["BIT-airflow-2020-17526","GHSA-7mx5-x372-xh87","PYSEC-2020-22"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Airflow","requires_auth":"low_privilege","summary":"Attackers can bypass authentication to access unauthorized Airflow instances using valid sessions from other sites.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"airflow","vendor":"apache"}],"cvss":{"score":7.7,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[],"description":"Incorrect Session Validation in Apache Airflow Webserver versions prior to 1.10.14 with default config allows a malicious airflow user on site A where they log in normally, to access unauthorized Airflow Webserver on Site B through the session from Site A.
