Deeper analysis

CVE-2026-24950 is an Authorization Bypass Through User-Controlled Key vulnerability (CWE-639) in the Authorsy WordPress plugin developed by themeplugs. It stems from exploiting incorrectly configured access control security levels, enabling insecure direct object references (IDOR). The issue affects Authorsy versions from n/a through 1.0.6 and was published on 2026-02-20 with a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high severity due to significant confidentiality impact.

Unauthenticated attackers can exploit this vulnerability remotely over the network with low complexity and no user interaction required. By leveraging user-controlled keys, they can bypass authorization checks, gaining unauthorized access to sensitive data without affecting integrity or availability.

The Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/authorsy/vulnerability/wordpress-authorsy-plugin-1-0-6-insecure-direct-object-references-idor-vulnerability?_s_id=cve details the IDOR vulnerability in Authorsy version 1.0.6, recommending mitigation through updating to a patched version beyond 1.0.6.
