Short explanation
A CSRF vulnerability in the SAML login flow of the Apache Airflow Amazon provider AWS auth manager allows an unauthenticated attacker to silently log a victim into the attacker's own account [S0]. This occurs because the login flow fails to bind the authentication response to the initiating browser [S0]. Users are advised to upgrade to version 9.38.0 [S0].
Attackers can exploit this vulnerability to redirect victims into attacker-controlled sessions, allowing subsequent actions performed by the victim to be controlled by the attacker [S0].
What should be done?
- Upgrade apache-airflow-providers-amazon to version 9.38.0
- Follow vendor advisory recommendations
Chain of evidence and sources
CVE-2026-86467, Apache Airflow Amazon provider içinde SAML oturum açma akışını etkileyen bir login-CSRF zafiyetidir [S0].
Zafiyet, AWS auth manager bileşeninin AuthnRequest kimliğini atmasından ve InResponseTo doğrulamasını yapmamasından kaynaklanır [S0].
Kullanıcıların apache-airflow-providers-amazon paketini 9.38.0 sürümüne yükseltmesi önerilir [S0].
Show the technical text from the sources
Apache Airflow Amazon provider: the AWS auth manager's SAML login flow does not bind the authentication response to the browser that began it. The login handler discards the AuthnRequest ID and the callback validates the assertion without requiring a matching InResponseTo, so an unauthenticated attacker who can cause a victim to load a page can complete a SAML login in the victim's browser using the attacker's own assertion, silently logging the victim into the attacker's Airflow account. Subsequent work the victim performs lands in a session the attacker controls. Affects deployments using the AWS auth manager with SAML authentication. The victim needs only to visit an attacker-controlled page; no Airflow account or credential is required of the attacker. This is the same login-CSRF class fixed in the Keycloak auth manager as CVE-2026-40948. Users of apache-airflow-providers-amazon are recommended to upgrade to version 9.38.0, which fixes the issue.
