CVE-2026-14245 — miniOrange OTP Login, Verification and SMS Notifications <= 5.5.1 - Authentication Bypass to Administrator Account Takeover via 'username_b' Parameter
The miniOrange OTP Login, Verification and SMS Notifications plugin for WordPress is vulnerable to Authentication Bypass leading to Administrator Account Takeover in all versions up to, and including, 5.5.1. This is due to the `um_reset_password_process_hook()` function performing no server-side verification that the OTP validation step was completed, and relying solely on a public `form_nonce` nonce that the plugin itself emits to unauthenticated visitors via the `moumprvar` JavaScript object on the Ultimate Member password reset page, while still accepting the attacker-controlled `username_b` parameter to target any WordPress user without role restriction or any binding to a previously validated OTP session. This makes it possible for unauthenticated attackers to obtain a freshly generated password-reset URL for an arbitrary Administrator account — returned in a 302 `Location` header — and use it to take full control of that account. Exploitation requires the Ultimate Member Password Reset Form integration to be active and the plugin to not be configured for phone-only reset.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- Technical severity (critical)+10
- Automatable exploitation (SSVC)+3
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Cyberlord92 miniOrange OTP Login, Verification and SMS Notifications).
- The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H (score shown at the top: security@wordfence.com) Weakness MITRE
Weakness class according to MITRE’s CWE catalog.
Detection
Read off the CVSS vector and the weakness class. Starting points, not tested rules.
- Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
- Audit administrative actions and access to resources outside each user’s normal pattern.
