Deeper analysis

CVE-2025-53217 is a missing authorization vulnerability (CWE-862) in the AIO WP Builder WordPress plugin by staviravn, identified as all-in-one-wp-builder. This flaw allows exploitation of incorrectly configured access control security levels and affects all versions of the plugin from unknown initial release through 2.0.2. The vulnerability was published on 2026-02-20 with a CVSS v3.1 base score of 7.6 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:H), rated as high severity.

The vulnerability enables exploitation over the network (AV:N) with low attack complexity (AC:L) by an attacker possessing low privileges (PR:L), requiring no user interaction (UI:N) and maintaining unchanged scope (S:U). Successful attacks can result in low confidentiality impact (C:L), such as limited data exposure, low integrity impact (I:L), like minor unauthorized modifications, and high availability impact (A:H), potentially causing significant service disruption.

AC-6 Least Privilege partial match
prevent

Implements least privilege to restrict low-privileged (PR:L) users from performing unauthorized actions exploited by this vulnerability.

SI-2 Flaw Remediation good match
prevent

Requires timely identification, reporting, and correction of flaws like the missing authorization in AIO WP Builder versions up to 2.0.2.
