Official description
The PublishPress Capabilities – User Role Editor, Access Permissions, User Capabilities, Admin Menus plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.50.0. This is due to the `addPluginCapabilities()` function unconditionally granting the Editor role all 15 `manage_capabilities_*` capabilities — including `manage_capabilities`, `manage_capabilities_roles`, `manage_capabilities_settings`, and `manage_capabilities_backup` — via a hard-coded `$eligible_roles = ['administrator', 'editor']` assignment that runs automatically on the first `admin_init` after plugin activation with no administrator opt-in, persisting the grants directly to the database. This makes it possible for authenticated attackers with Editor-level access to elevate their privileges to a site-wide capability manager, enabling them to create, rename, and delete non-system roles, modify capabilities of non-administrator roles, restore role backups, and write arbitrary plugin options whose names begin with `cme_`, `capsman`, `pp_capabilities`, or `presspermit` via `update_option()`. The escalation stops short of full Administrator access, as WordPress's `map_meta_cap` layer still prevents the escalated Editor from granting administrator-only capabilities to other roles; however, all role-management and plugin-settings functionality gated solely on `manage_capabilities_*` capabilities remains fully accessible.

The underlying weakness: Improper Privilege Management
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
