Deeper analysis
CVE-2025-69311 is a Missing Authorization vulnerability (CWE-862) in the Broadstreet Ads WordPress plugin, also referred to as broadstreet. The flaw enables exploiting incorrectly configured access control security levels and affects all versions from n/a through 1.52.1. Published on 2026-01-22, it carries a CVSS v3.1 base score of 7.6 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L), indicating high severity due to network accessibility and significant confidentiality impact.
A remote attacker with low privileges, such as a subscribed or contributor-level WordPress user, can exploit this vulnerability over the network with low complexity and no user interaction required. Exploitation allows high-impact unauthorized access to sensitive data (C:H), alongside low-impact modifications (I:L) and denial of service (A:L) within the plugin's scope, without changing the overall system scope.
The Patchstack advisory (https://patchstack.com/database/Wordpress/Plugin/broadstreet/vulnerability/wordpress-broadstreet-ads-plugin-1-52-1-broken-access-control-vulnerability?_s_id=cve) documents this as a broken access control issue in Broadstreet Ads version 1.52.1.
