Summary

CVE-2026-85984 is a critical authentication bypass vulnerability in the miniOrange OTP Login, Verification and SMS Notifications WordPress plugin, affecting versions up to and including 5.5.5. The flaw allows unauthenticated attackers to log in as any existing user — including administrators — by supplying only a known username and an empty password. With a CVSS v3.1 score of 9.8 (Critical), successful exploitation results in full administrative takeover of the WordPress site.

Technical details

  • Root cause: The plugin’s WordPress login form handling fails to properly validate password/OTP verification when the mo_wp_login_intent request parameter is set (e.g., to otp), allowing the login flow to skip password checks under certain configurations.
  • Trigger conditions: Exploitation requires specific plugin settings to be enabled, including "WP Login OTP," "Login with Only OTP," "Allow Users to Login with Username and Password," and "Admin OTP Bypass."
  • Attack vector: Network-based, unauthenticated (AV:N, PR:N, UI:N) — an attacker submits a login request with a known/guessed username, an empty password, and the crafted mo_wp_login_intent parameter.
  • Impact: Complete compromise of confidentiality, integrity, and availability, as the attacker can authenticate as an administrator without valid credentials, leading to full site takeover.

Affected software

  • miniOrange OTP Login, Verification and SMS Notifications (WordPress plugin, vendor: cyberlord92) — versions 0 through 5.5.5, when the affected login settings are enabled.

Severity

  • CVSS v3.1 Base Score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Update the miniOrange OTP Login, Verification and SMS Notifications plugin to version 5.5.6 or later, which hardens the WordPress login form’s administrator OTP-bypass flow so that a verified password or OTP is always required before a session is issued.
  • If patching is not immediately possible: Disable the "Login with Only OTP," "WP Login OTP," and "Admin OTP Bypass" settings until the update can be applied; monitor authentication logs for anomalous login requests containing the mo_wp_login_intent parameter; consider restricting access to wp-login.php at the network layer for untrusted sources.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
