Summary

CVE-2026-14364 is an unauthenticated account takeover vulnerability in the TrueBooker – Appointment Booking and Scheduler System plugin for WordPress (vendor themetechmount), affecting all versions up to and including 1.2.3. The plugin fails to properly validate a user’s identity before resetting their password, allowing attackers to seize arbitrary accounts, including administrators. It carries a CRITICAL CVSS v3.1 base score of 9.8.

Technical details

  • Root cause: The plugin does not properly validate a user’s identity before resetting their password (CWE-640: Weak Password Recovery Mechanism for Forgotten Password).
  • Trigger conditions: No authentication required; an attacker abuses the plugin’s password reset flow to set a new password on a targeted account.
  • Attack vector: Network — remotely exploitable over HTTP/HTTPS against an internet-facing WordPress site running the plugin.
  • Impact: Attackers can reset the password of arbitrary user accounts, including administrators, and gain full access to those accounts, leading to complete site compromise.

Affected software

  • TrueBooker – Appointment Booking and Scheduler System for WordPress: all versions up to and including 1.2.3.

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 TrueBooker plugin to a fixed release later than 1.2.3 (the fix was published in the plugin’s source changeset following 1.2.3). Apply the latest available version.
  • If no patch can be applied: Deactivate and remove the plugin until it can be updated. Restrict access to the site’s front end and login/password-reset endpoints via a WAF or network controls, and audit user accounts for unexpected password changes or new administrator accounts.

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.
