Descripción técnica

The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.13.1 This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to view privacy-restricted member profile field values — including fields explicitly configured as owner-only, members-only, or role-restricted — by querying the publicly accessible wp_ajax_nopriv_um_get_members endpoint. The nonce required by the endpoint ('um-frontend-nonce') is emitted to all unauthenticated visitors via wp_localize_script, meaning it provides no meaningful access control and any anonymous visitor can satisfy the endpoint's authentication requirements.

———OCO-Server is a self-hosted endpoint management application for computer inventory, software deployment, and mobile device management. Prior to 1.2.3, a valid Self-Service Portal user with permission to create job containers and read visibility on a computer and package can queue an uninstall job without deploy permission for those resources. Requests to `self-service/ajax-handler/job-containers.php` pass `uninstall_package_assignment_id[]` values to `lib/SelfService/CoreLogic.class.php::uninstallSelfService()`. Its permission-check loop continues after denied `METHOD_DEPLOY` checks without removing rejected IDs from `$installationIds`, then passes the original list to `lib/CoreLogic.class.php::uninstall()`. The CoreLogic object is constructed with a null SystemUser, causing `lib/CoreLogic.class.php::checkPermission()` to treat the operation as system context and unconditionally permit it. Enumerable `computer_package.id` values allow selection of readable installed-package assignments, including those on other users' computers. The `deploySelfService()` install path instead aborts on denied deployment permission, and resources lacking read permission remain blocked. This permits unauthorized software-removal jobs across resources visible to the acting user's role. This issue is fixed in version 1.2.3.5h CVE-2026-1153237.3 ALT
