CVE-2025-11127
At a glance
CVE-2025-11127 is a critical-severity Authorization Bypass Through User-Controlled Key vulnerability in the Mstore Mobile App WordPress plugin, affecting versions <= 2.08. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed October 2025, reported by Khaled Alenazi (Nxploited).
Vulnerability Overview
Multiple plugins and/or themes for WordPress are vulnerable to Privilege Escalation in various versions. This is due to 'mstoreapp-google_connect' AJAX endpoint not properly verifying a user's identify prior to authenticating them. This makes it possible for unauthenticated attackers to to gain access to other user's accounts that have a higher privilege.
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 privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-639: Authorization Bypass Through User-Controlled Key
Mstore Mobile App <= 2.08 carries this weakness at mstoreapp-google_connect, and reaching it takes no account at all. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.
Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. No fixed build of this plugin is recorded for Mstore Mobile App yet, so installs running <= 2.08 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?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
