CVE-2026-86466 (GCVE-0-2026-86466)

Vulnerability from nvd – Published: 2026-09-16 09:12 – Updated: 2026-09-17 19:21

Title

Apache Airflow FAB provider: FAB Authentik provider: id_token issuer/audience not validated

Summary

Apache Airflow FAB provider: the Authentik OAuth path in the FAB auth manager does not validate the issuer or audience claims of the id_token it accepts. An attacker holding a token that the same Authentik identity provider minted for a different client application can present it to Airflow and be authenticated as the user it names, because the audience claim is never checked. Affects deployments using the FAB auth manager with Authentik OAuth where the same Authentik instance also serves other applications; the attacker needs a valid token for any of those other applications, not for Airflow. CVE-2026-75156 corrected the same missing validation on the Azure AD path in this file; the Authentik path was left unchanged and is fixed here. Deployments that applied the CVE-2026-75156 fix and use Authentik must also upgrade for this one. Users of apache-airflow-providers-fab are recommended to upgrade to version 3.9.0 or later, which fixes the issue.

CVE-2026-82310 (GCVE-0-2026-82310)

Vulnerability from nvd – Published: 2026-09-16 09:09 – Updated: 2026-09-17 19:23

Title

Apache Airflow FAB provider: FAB auth manager: deactivated users retain and renew Core API JWT access

Summary

Apache Airflow FAB provider: deactivating a user account does not stop tokens issued to that account before deactivation. Password authentication correctly rejects the disabled account, but the Core API continues to accept an existing, unexpired token naming it, and lets that token mint a replacement — so the account keeps its role-scoped access indefinitely after an administrator has disabled it. The user replays their own legitimate credential; no signature forgery or privilege escalation is involved, and the access stays within the roles the account already held. Affects deployments using Airflow 3 with the FAB auth manager and Core API token authentication, where an administrator deactivates an account whose row remains in the database and whose previously issued token has not expired. The trigger is administrative deactivation as a containment action, which silently fails to contain. Users of apache-airflow-providers-fab are recommended to upgrade to version 3.9.0 or later, which rejects tokens naming a deactivated account.

CVE-2026-86462 (GCVE-0-2026-86462)

Vulnerability from nvd – Published: 2026-09-16 09:05 – Updated: 2026-09-17 19:24

Title

Apache Airflow FAB provider: FAB Admin password PATCH does not invalidate database-backed sessions

Summary

Apache Airflow FAB provider: changing a user's password through the Admin user-edit PATCH endpoint does not invalidate that user's existing database-backed sessions. An attacker who already holds a copy of the victim's session cookie keeps full access as that user after the password change, so the password reset does not evict them. Affects deployments using the FAB auth manager with database-backed sessions; an administrator (or the user themselves) performing a routine password change is the trigger, and no attacker interaction with the endpoint is needed. This is a second, independent route to the outcome addressed by CVE-2026-82311, which corrected an identifier comparison in the session-invalidation helper. That fix does not repair this endpoint, because the PATCH path never calls the helper at all. Deployments that applied the CVE-2026-82311 fix must also upgrade for this one. Users of apache-airflow-providers-fab are recommended to upgrade to version 3.9.0 or later, which fixes the issue.

CVE-2026-82311 (GCVE-0-2026-82311)

Vulnerability from nvd – Published: 2026-09-16 09:00 – Updated: 2026-09-17 19:27

Title

Apache Airflow FAB provider: FAB password reset never invalidates sessions: string/int _user_id comparison is always false

Summary

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. Affects 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. apache-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. Users of apache-airflow-providers-fab are recommended to upgrade to version 3.9.0 or later, which compares the identifiers consistently.

CVE-2026-75156 (GCVE-0-2026-75156)

Vulnerability from nvd – Published: 2026-09-08 16:47 – Updated: 2026-09-16 14:57

Title

Apache Airflow FAB provider: FAB Azure AD OAuth: id_token issuer/audience not validated — cross-tenant authentication bypass

Summary

Apache Airflow FAB provider versions 3.7.3 through 3.8.0 do not validate the issuer or audience of Azure AD `id_token`s during OAuth login. Deployments are affected only when the FAB auth manager is configured with Azure AD as an OAuth provider. Because the signing keys are fetched from Microsoft's **multi-tenant** JWKS endpoint, an `id_token` minted in *any* Azure tenant — including one the attacker creates — passes signature verification, and the username and role assignments are then read from that attacker-controlled token. Anyone able to register an Azure tenant can therefore authenticate to the Airflow UI with no prior access to the deployment. The fix for **CVE-2026-59243** was incomplete, and this advisory closes the remaining gap: that fix made the provider verify the `id_token` signature, but did not add issuer or audience checks. Operators who already applied the CVE-2026-59243 fix are **still affected and must upgrade again** — 3.7.3 is the release that shipped that fix, so every version containing it falls inside this affected range. Upgrade to apache-airflow-providers-fab `3.8.1` or later.

CVE-2026-59243 (GCVE-0-2026-59243)

Vulnerability from nvd – Published: 2026-07-29 08:35 – Updated: 2026-09-16 14:56

Title

Apache Airflow FAB provider: FAB auth manager: JWT signature verification disabled by default for Azure AD OAuth (`verify_signature` defaults to `False`)

Summary

The FAB auth manager's Azure AD OAuth login defaulted `verify_signature=False` when decoding the ID token, so an attacker able to present a forged or unsigned (`alg:none`) ID token to the OAuth callback could bypass authentication and log in as an arbitrary user, including one holding the Admin role (CWE-347). Deployments running the FAB auth manager with the Azure AD OAuth login path under its default configuration are affected; the Authentik path already defaulted to `True`. This issue affects `apache-airflow-providers-fab` before 3.7.3. Users are advised to upgrade to `apache-airflow-providers-fab` 3.7.3, which defaults `verify_signature=True`.

CVE-2026-59245 (GCVE-0-2026-59245)

Vulnerability from nvd – Published: 2026-07-13 15:05 – Updated: 2026-09-16 14:55

Title

Apache Airflow FAB provider: FAB auth manager: a DAG named "DAGs" hijacks the global all-DAGs permission (access_control privilege escalation via resource_name() collision)

Summary

In the Apache Airflow FAB auth manager, a DAG whose `dag_id` is `DAGs` collided with the global all-DAGs permission resource name produced by `resource_name()`, so a user granted per-DAG `access_control` on that one DAG was silently granted the global all-DAGs permission (privilege escalation). The escalation triggers when a DAG named `DAGs` exists and a lower-privileged user is given per-DAG access to it, granting that user read/edit access to every DAG. Users are advised to upgrade to `apache-airflow-providers-fab` 3.7.2 or later, which disambiguates the resource-name collision.

Severity

8.1 (High)

CVE-2024-45033 (GCVE-0-2024-45033)

Vulnerability from nvd – Published: 2025-01-08 08:41 – Updated: 2025-01-08 13:59

Title

Apache Airflow Fab Provider: Application does not invalidate session after password change via Airflow cli

Summary

Insufficient Session Expiration vulnerability in Apache Airflow Fab Provider. This issue affects Apache Airflow Fab Provider: before 1.5.2. When user password has been changed with admin CLI, the sessions for that user have not been cleared, leading to insufficient session expiration, thus logged users could continue to be logged in even after the password was changed. This only happened when the password was changed with CLI. The problem does not happen in case change was done with webserver thus this is different from CVE-2023-40273 https://github.com/advisories/GHSA-pm87-24wq-r8w9 which was addressed in Apache-Airflow 2.7.0 Users are recommended to upgrade to version 1.5.2, which fixes the issue.

Severity

8.1 (High)

Summary

Insufficient Session Expiration vulnerability in Apache Airflow Providers FAB. This issue affects Apache Airflow Providers FAB: 1.2.1 (when used with Apache Airflow 2.9.3) and FAB 1.2.0 for all Airflow versions. The FAB provider prevented the user from logging out. * FAB provider 1.2.1 only affected Airflow 2.9.3 (earlier and later versions of Airflow are not affected) * FAB provider 1.2.0 affected all versions of Airflow. Users who run Apache Airflow 2.9.3 are recommended to upgrade to Apache Airflow Providers FAB version 1.2.2 which fixes the issue. Users who run Any Apache Airflow version and have FAB provider 1.2.0 are recommended to upgrade to Apache Airflow Providers FAB version 1.2.2 which fixes the issue. Also upgrading Apache Airflow to latest version available is recommended. Note: Early version of Airflow reference container images of Airflow 2.9.3 and constraint files contained FAB provider 1.2.1 version, but this is fixed in updated versions of the images. Users are advised to pull the latest Airflow images or reinstall FAB provider according to the current constraints.

CVE-2026-86466 (GCVE-0-2026-86466)

Vulnerability from cvelistv5 – Published: 2026-09-16 09:12 – Updated: 2026-09-17 19:21

Title

Apache Airflow FAB provider: FAB Authentik provider: id_token issuer/audience not validated

Summary

Apache Airflow FAB provider: the Authentik OAuth path in the FAB auth manager does not validate the issuer or audience claims of the id_token it accepts. An attacker holding a token that the same Authentik identity provider minted for a different client application can present it to Airflow and be authenticated as the user it names, because the audience claim is never checked. Affects deployments using the FAB auth manager with Authentik OAuth where the same Authentik instance also serves other applications; the attacker needs a valid token for any of those other applications, not for Airflow. CVE-2026-75156 corrected the same missing validation on the Azure AD path in this file; the Authentik path was left unchanged and is fixed here. Deployments that applied the CVE-2026-75156 fix and use Authentik must also upgrade for this one. Users of apache-airflow-providers-fab are recommended to upgrade to version 3.9.0 or later, which fixes the issue.

CVE-2026-82310 (GCVE-0-2026-82310)

Vulnerability from cvelistv5 – Published: 2026-09-16 09:09 – Updated: 2026-09-17 19:23

Title

Apache Airflow FAB provider: FAB auth manager: deactivated users retain and renew Core API JWT access

Summary

Apache Airflow FAB provider: deactivating a user account does not stop tokens issued to that account before deactivation. Password authentication correctly rejects the disabled account, but the Core API continues to accept an existing, unexpired token naming it, and lets that token mint a replacement — so the account keeps its role-scoped access indefinitely after an administrator has disabled it. The user replays their own legitimate credential; no signature forgery or privilege escalation is involved, and the access stays within the roles the account already held. Affects deployments using Airflow 3 with the FAB auth manager and Core API token authentication, where an administrator deactivates an account whose row remains in the database and whose previously issued token has not expired. The trigger is administrative deactivation as a containment action, which silently fails to contain. Users of apache-airflow-providers-fab are recommended to upgrade to version 3.9.0 or later, which rejects tokens naming a deactivated account.

CVE-2026-86462 (GCVE-0-2026-86462)

Vulnerability from cvelistv5 – Published: 2026-09-16 09:05 – Updated: 2026-09-17 19:24

Title

Apache Airflow FAB provider: FAB Admin password PATCH does not invalidate database-backed sessions

Summary

Apache Airflow FAB provider: changing a user's password through the Admin user-edit PATCH endpoint does not invalidate that user's existing database-backed sessions. An attacker who already holds a copy of the victim's session cookie keeps full access as that user after the password change, so the password reset does not evict them. Affects deployments using the FAB auth manager with database-backed sessions; an administrator (or the user themselves) performing a routine password change is the trigger, and no attacker interaction with the endpoint is needed. This is a second, independent route to the outcome addressed by CVE-2026-82311, which corrected an identifier comparison in the session-invalidation helper. That fix does not repair this endpoint, because the PATCH path never calls the helper at all. Deployments that applied the CVE-2026-82311 fix must also upgrade for this one. Users of apache-airflow-providers-fab are recommended to upgrade to version 3.9.0 or later, which fixes the issue.

CVE-2026-82311 (GCVE-0-2026-82311)

Vulnerability from cvelistv5 – Published: 2026-09-16 09:00 – Updated: 2026-09-17 19:27

Title

Apache Airflow FAB provider: FAB password reset never invalidates sessions: string/int _user_id comparison is always false

Summary

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. Affects 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. apache-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. Users of apache-airflow-providers-fab are recommended to upgrade to version 3.9.0 or later, which compares the identifiers consistently.

CVE-2026-75156 (GCVE-0-2026-75156)

Vulnerability from cvelistv5 – Published: 2026-09-08 16:47 – Updated: 2026-09-16 14:57

Title

Apache Airflow FAB provider: FAB Azure AD OAuth: id_token issuer/audience not validated — cross-tenant authentication bypass

Summary

Apache Airflow FAB provider versions 3.7.3 through 3.8.0 do not validate the issuer or audience of Azure AD `id_token`s during OAuth login. Deployments are affected only when the FAB auth manager is configured with Azure AD as an OAuth provider. Because the signing keys are fetched from Microsoft's **multi-tenant** JWKS endpoint, an `id_token` minted in *any* Azure tenant — including one the attacker creates — passes signature verification, and the username and role assignments are then read from that attacker-controlled token. Anyone able to register an Azure tenant can therefore authenticate to the Airflow UI with no prior access to the deployment. The fix for **CVE-2026-59243** was incomplete, and this advisory closes the remaining gap: that fix made the provider verify the `id_token` signature, but did not add issuer or audience checks. Operators who already applied the CVE-2026-59243 fix are **still affected and must upgrade again** — 3.7.3 is the release that shipped that fix, so every version containing it falls inside this affected range. Upgrade to apache-airflow-providers-fab `3.8.1` or later.

CVE-2026-59243 (GCVE-0-2026-59243)

Vulnerability from cvelistv5 – Published: 2026-07-29 08:35 – Updated: 2026-09-16 14:56

Title

Apache Airflow FAB provider: FAB auth manager: JWT signature verification disabled by default for Azure AD OAuth (`verify_signature` defaults to `False`)

Summary

The FAB auth manager's Azure AD OAuth login defaulted `verify_signature=False` when decoding the ID token, so an attacker able to present a forged or unsigned (`alg:none`) ID token to the OAuth callback could bypass authentication and log in as an arbitrary user, including one holding the Admin role (CWE-347). Deployments running the FAB auth manager with the Azure AD OAuth login path under its default configuration are affected; the Authentik path already defaulted to `True`. This issue affects `apache-airflow-providers-fab` before 3.7.3. Users are advised to upgrade to `apache-airflow-providers-fab` 3.7.3, which defaults `verify_signature=True`.

CVE-2026-59245 (GCVE-0-2026-59245)

Vulnerability from cvelistv5 – Published: 2026-07-13 15:05 – Updated: 2026-09-16 14:55

Title

Apache Airflow FAB provider: FAB auth manager: a DAG named "DAGs" hijacks the global all-DAGs permission (access_control privilege escalation via resource_name() collision)

Summary

In the Apache Airflow FAB auth manager, a DAG whose `dag_id` is `DAGs` collided with the global all-DAGs permission resource name produced by `resource_name()`, so a user granted per-DAG `access_control` on that one DAG was silently granted the global all-DAGs permission (privilege escalation). The escalation triggers when a DAG named `DAGs` exists and a lower-privileged user is given per-DAG access to it, granting that user read/edit access to every DAG. Users are advised to upgrade to `apache-airflow-providers-fab` 3.7.2 or later, which disambiguates the resource-name collision.

Severity

8.1 (High)

CVE-2024-45033 (GCVE-0-2024-45033)

Vulnerability from cvelistv5 – Published: 2025-01-08 08:41 – Updated: 2025-01-08 13:59

Title

Apache Airflow Fab Provider: Application does not invalidate session after password change via Airflow cli

Summary

Insufficient Session Expiration vulnerability in Apache Airflow Fab Provider. This issue affects Apache Airflow Fab Provider: before 1.5.2. When user password has been changed with admin CLI, the sessions for that user have not been cleared, leading to insufficient session expiration, thus logged users could continue to be logged in even after the password was changed. This only happened when the password was changed with CLI. The problem does not happen in case change was done with webserver thus this is different from CVE-2023-40273 https://github.com/advisories/GHSA-pm87-24wq-r8w9 which was addressed in Apache-Airflow 2.7.0 Users are recommended to upgrade to version 1.5.2, which fixes the issue.

Severity

8.1 (High)

Title

Apache Airflow Providers FAB: FAB provider 1.2.1 and 1.2.0 did not let user to logout for Airflow

Summary

Insufficient Session Expiration vulnerability in Apache Airflow Providers FAB. This issue affects Apache Airflow Providers FAB: 1.2.1 (when used with Apache Airflow 2.9.3) and FAB 1.2.0 for all Airflow versions. The FAB provider prevented the user from logging out. * FAB provider 1.2.1 only affected Airflow 2.9.3 (earlier and later versions of Airflow are not affected) * FAB provider 1.2.0 affected all versions of Airflow. Users who run Apache Airflow 2.9.3 are recommended to upgrade to Apache Airflow Providers FAB version 1.2.2 which fixes the issue. Users who run Any Apache Airflow version and have FAB provider 1.2.0 are recommended to upgrade to Apache Airflow Providers FAB version 1.2.2 which fixes the issue. Also upgrading Apache Airflow to latest version available is recommended. Note: Early version of Airflow reference container images of Airflow 2.9.3 and constraint files contained FAB provider 1.2.1 version, but this is fixed in updated versions of the images. Users are advised to pull the latest Airflow images or reinstall FAB provider according to the current constraints.
