At a glance
CVE-2025-11620 is a high-severity Missing Authorization vulnerability in the Multiple Roles per User WordPress plugin, affecting versions <= 1.0. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Custom level or above. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed November 2025, reported by Jonas Benjamin Friedli.
Vulnerability Overview
The Multiple Roles per User plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'mrpu_add_multiple_roles_ui' and 'mrpu_save_multiple_user_roles' functions in all versions up to, and including, 1.0. This makes it possible for authenticated attackers, granted the 'edit_users' capability, to edit any user's role, including promoting users to Administrator and demoting Administrators to lower-privileged roles.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-862: Missing Authorization
Multiple Roles per User <= 1.0 carries this weakness at mrpu_add_multiple_roles_ui, and reaching it takes an account at Custom level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. No fixed build of this plugin is recorded for Multiple Roles per User yet, so installs running <= 1.0 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
