Description

The MemberPress plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.14.1. This is due to a bypassable nonce verification check in the save_profile_fields() function that uses an isset() condition at line 1119, allowing the security check to be completely bypassed by simply omitting the nonce parameter from the request. This makes it possible for unauthenticated attackers to change authenticated users' email addresses via a forged request granted they can trick an authenticated user into performing an action such as clicking on a link, leading to account takeover through password reset functionality.

Detection & mitigation playbook

Vulnerability

  1. Detect

    Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

  2. Remediation status

    No fixed release is recorded for CVE-2026-92797 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.

  3. Mitigate without a patch

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
