Apache Airflow Fab Provider

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.

Apache Airflow FAB Auth Manager contains an LDAP filter injection vulnerability (CWE-90) that allows unauthenticated attackers to exfiltrate directory data or bypass authentication. Upgrade to apache-airflow-providers-fab 3.6.4 or later. If immediate upgrade is not possible, disable LDAP authentication until the provider can be updated.

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.
