The Ultimate Member WordPress plugin before 2.13.0 does not validate a submitted role selection when it cannot resolve the set of roles a profile form permits, and screens the value against the site's registered role names rather than against the form's own allow-list, allowing unauthenticated users who register through the Ultimate Member WordPress plugin before 2.13.0's own form to grant themselves arbitrary capabilities and reach administrator-equivalent access.

CVE-2026-554858.8 ALT—
——0Piccolo Admin is an admin interface and content management system for Python, built on top of Piccolo. Prior to 1.14.0, piccolo_admin/endpoints.py uses superuser_validators to block PUT, PATCH, DELETE, and POST requests by non-superusers but permits GET requests to configured user and session tables, while piccolo_api/session_auth/tables.py exposes SessionsBase.token because the token column is not secret. In deployments that add the Sessions and User tables to create_admin, a non-superuser administrator can call GET /api/tables/sessions/, obtain another user's live session token, replay it as the Cookie id value to impersonate a superuser, and permanently set superuser to true on the attacker's own row. This issue is fixed in version 1.14.0.23hCVE-2026-799967.2 ALT3.8%
——1The User Registration & Membership WordPress plugin before 5.2.6 does not perform a capability check when saving its login settings, allowing authenticated users who have been granted a User Registration & Membership WordPress plugin before 5.2.6 management capability but not full administrator access to change arbitrary site options and escalate their privileges to administrator.1dCVE-2026-78174—23.0%
——7WatchGuard Dimension records unredacted session identifiers for logged-in users in its web UI diagnostic log. A low-privileged Dimension Administrator can retrieve this log and extract a Super Administrator's session token while that administrator is logged in, enabling account takeover.23hCVE-2026-81818—23.1%
——7Affected versions of Flowintel contain an authorization flaw in the administrative user-edit API.
The existing authorization check correctly prevented an organization administrator from editing users in another organization, but it did not prevent them from editing a full administrator within their own organization. As a result, an org admin could modify that full administrator account, including changing its password. The upstream commit explicitly describes the issue as:
“Org admin can change the password of a full admin in the same organization.”
The fix adds a higher-privilege boundary check:
if user_to_edit.is_admin(): return ... 403
so organization administrators can no longer modify full administrator accounts.

——5The CMP WordPress plugin before 4.1.18 does not enforce an option-name allow-list when importing settings via one of its AJAX actions, allowing users with the Editor role (when the administrator has granted the Editor role access to the CMP WordPress plugin before 4.1.18's admin-bar controls) to update arbitrary WordPress options, including options that lead to privilege escalation to Administrator.1dCVE-2026-792764.3 MED13.5%
——4Improper privilege management in FileSystem in Google Chrome prior to 152.0.7977.65 allowed a remote attacker leveraging social engineering to bypass system access restrictions via a crafted HTML page. (Chromium security severity: Medium)23h
