Deeper analysis

CVE-2025-53763 is an improper access control vulnerability (CWE-284) in Azure Databricks. Published on 2025-08-21, it carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). The flaw enables an unauthorized attacker to elevate privileges over a network.

The vulnerability can be exploited by any unauthenticated attacker (PR:N) remotely over the network (AV:N), with low attack complexity (AC:L) and no user interaction required (UI:N). Successful exploitation results in high impacts to confidentiality, integrity, and availability (C:H/I:H/A:H), allowing privilege elevation without changing scope (S:U).

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match
prevent

Enforces approved authorizations for access to system resources, directly mitigating the improper access control that allows unauthorized privilege elevation.

AC-6 Least Privilege good match
prevent

Employs least privilege principle to restrict access rights, preventing unauthorized attackers from escalating privileges.

AC-24 Access Control Decisions good match
prevent

Determines and authorizes access based on defined policies, countering flaws in access control decisions exploited for privilege elevation.
