CVE-2025-3844 — The PeproDev Ultimate Profile Solutions plugin for WordPress is vulnerable to Authentication Bypass in versions 1.9.1 to 7.5.2

Critical CVSS 9.8

The PeproDev Ultimate Profile Solutions plugin for WordPress is vulnerable to Authentication Bypass in versions 1.9.1 to 7.5.2. This is due to handel_ajax_req() function not having proper restrictions on the change_user_meta functionality that makes it possible to set a OTP code and subsequently log in with that OTP code. This makes it possible for unauthenticated attackers to login as other users on the site, including administrators.

Matched remediation archetype

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
