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-2026-82311 in the wild and no public exploit code.\n\nAffected product: Apache Airflow FAB provider. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-82311/ (Markdown: https://insights.sbomify.com/CVE-2026-82311/index.md)","id":"CVE-2026-82311","markdown":"https://insights.sbomify.com/CVE-2026-82311/index.md","name":"CVE-2026-82311","record":{"aliases":["CLEANSTART-2026-GK10237","GHSA-gr7m-j34w-7qcm"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Airflow FAB provider","requires_auth":"none","summary":"Attackers retain access via stolen session cookies after password resets due to a type mismatch in session invalidation logic within the Apache Airflow FAB provider.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"apache-airflow-providers-fab","vendor":"apache"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-613","name":"DEPRECATED: Insufficient Session Expiration"}],"description":"Apache Airflow FAB provider: resetting a user's password does not delete that user's existing database-backed sessions, despite documented behaviour that it does. The cleanup compares the string identifier Flask-Login stores in the session against the user's integer database identifier, so the comparison never matches and no session is removed. An attacker who already holds a copy of the victim's session cookie keeps access as that user after the password change, so the reset does not evict them.\n\nAffects deployments using the FAB auth manager with `[fab] session_backend=database`. The trigger is an administrator (or the user) running the supported password-reset command as a containment action after a session cookie has been compromised; the secure-cookie backend is out of scope, as it documents that it cannot centrally delete sessions.\n\napache-airflow-providers-fab 3.9.0 also fixes CVE-2026-86462, a second, independent route to the same outcome via the Admin user-edit endpoint; a single upgrade closes both.\n\nUsers of apache-airflow-providers-fab are recommended to upgrade to version 3.9.0 or later, which compares the identifiers consistently.","ecosystems":[],"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":"Security feature bypass in Apache Airflow FAB provider","id":"CVE-2026-82311","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Denial of service in OpenVPN","id":"CVE-2026-82312"},"packages":[],"prev":{"headline":"Apache Airflow FAB provider: FAB auth manager: deactivated users retain and renew Core API JWT access","id":"CVE-2026-82310"},"products":["Apache Airflow FAB provider"],"published":"2026-09-16","related":[{"cvss_score":9.8,"headline":"Auth bypass in Apache Airflow FAB provider","id":"CVE-2026-59243","kev_date_added":null,"published":"2026-07-29"},{"cvss_score":9.8,"headline":"Apache Airflow Providers FAB: FAB provider 1.2.1 and 1.2.0 did not let user to logout for Airflow","id":"CVE-2024-42447","kev_date_added":null,"published":"2024-08-05"},{"cvss_score":9.1,"headline":"Apache Airflow FAB provider: FAB Admin password PATCH does not invalidate database-backed sessions","id":"CVE-2026-86462","kev_date_added":null,"published":"2026-09-16"},{"cvss_score":9.1,"headline":"Auth bypass in Apache Airflow FAB provider","id":"CVE-2026-75156","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":8.1,"headline":"Apache Airflow FAB provider: FAB Authentik provider: id_token issuer/audience not validated","id":"CVE-2026-86466","kev_date_added":null,"published":"2026-09-16"},{"cvss_score":8.1,"headline":"Privilege escalation in Apache Airflow FAB provider","id":"CVE-2026-59245","kev_date_added":null,"published":"2026-07-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-17","vendors":["Apache Software Foundation"]},"summary":"Attackers retain access via stolen session cookies after password resets due to a type mismatch in session invalidation logic within the Apache Airflow FAB provider.","url":"https://insights.sbomify.com/CVE-2026-82311/"}
