Critical CVSS 9.8
CVE-2026-12394
The MemberGlut WordPress plugin before 1.1.5 does not validate the role chosen during front-end registration, allowing unauthenticated users to register an account with an arbitrary role, including administrator, leading to full site compromise.
What this means
- Exposure
- Exploitable remotely over the network, without authentication and with no action from the victim.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline.
- Weakness
- Privilege handling is faulty, so an account ends up with more rights than intended.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
