CVE-2026-16310
CRITICALCVE-2026-16310 allows unauthenticated attackers to change any WordPress user's password via an insecure direct object reference in the MemberDash plugin.
The MemberDash WordPress plugin lacks validation on the 'id' parameter, enabling attackers to alter any user's password during registration and hijack accounts without alerting victims. DIB organizations using WordPress must patch this plugin immediately to prevent credential theft and unauthorized access, as the flaw directly undermines identity and access management controls required by NIST 800-171.
Shame score — A critical flaw allowing unauthenticated account takeover via a simple ID parameter bypass is avoidable and directly compromises user identity and access management, a core NIST 800-171 requirement.
▸ RECOMMENDED ACTION Critical severity — schedule patching of the affected products.
The MemberDash plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.8.5 via the 'id' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to change the password of any WordPress user, including administrators, by supplying an arbitrary user ID during registration, and take over their account without any notification sent to the victim.
