Apache Airflow: Improper Preservation of Permissions

CVE-2024-28746 is a high-severity improper preservation of permissions vulnerability in Apache Airflow from Apache, with a CVSS 3.1 base score of 8.1 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 2.8.3 as the first without the flaw, so updating Apache Airflow to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.33% chance of exploitation within 30 days, higher than 72% of scored CVEs.

The underlying weakness: Improper Preservation of Permissions

The product does not preserve permissions or incorrectly preserves permissions when copying, restoring, or sharing objects, which can cause them to have less restrictive permissions than intended.
