CVE-2026-14545: TrueBooker Appointment Booking < 1.2.4 - Unauthenticated Account Takeover via Password Reset

The TrueBooker WordPress plugin before 1.2.4 does not validate account ownership when resetting a user's password through one of its front-end account handlers, allowing unauthenticated attackers to set an arbitrary password on any account, including an administrator, and take over the site.

Security readout for executives and security teams

Plain-English summary

TrueBooker versions before 1.2.4 reportedly let anyone reset another user’s password without proving account ownership. An attacker could seize an administrator account, control the WordPress site, access sensitive information, alter content, or disrupt service. No prior login or user interaction is required.

Executive priority

Act immediately on internet-facing installations. The reported flaw can convert one unauthenticated request path into full administrative control, creating confidentiality, integrity, and availability risk. Patch or isolate affected sites, then investigate for account changes. Evidence of exploitation in the wild is currently absent from the supplied sources.

Technical view

A front-end account handler fails to validate ownership during password reset. The network-accessible flaw requires low complexity, no privileges, and no user interaction. It can permit an arbitrary password change for any account, including administrators. The supplied record assigns CVSS 3.1 score 9.8 and CWE-269.

Likely exposure

Internet-accessible WordPress sites running TrueBooker earlier than 1.2.4 are likely exposed, particularly when the vulnerable front-end account functionality is reachable. The bundle’s structured affected-version field is inconsistent, listing version “0,” so confirm installed versions and applicability against WPScan or vendor guidance.

Exploitation context

The source bundle identifies a direct unauthenticated account-takeover path and tags the WPScan reference as exploit-related. However, it provides no evidence of active exploitation, and the CVE is not listed as KEV. Treat exploitation status as unconfirmed while prioritizing remediation because attack prerequisites are minimal.

Researcher notes

The stated vulnerable range is releases before 1.2.4, but the structured affected data lists only version “0” with default status unaffected. This inconsistency limits precise machine-readable scoping. Validate applicability through the CVE record and WPScan entry. No exploit mechanics, vendor advisory details, or confirmed exploitation telemetry are included in the bundle.

Mitigation direction

  • Update TrueBooker to version 1.2.4 or later after confirming vendor guidance.
  • Disable or remove TrueBooker if updating cannot be completed promptly.
  • Restrict access to affected front-end account handlers until remediation is verified.
  • Reset privileged credentials and review administrator accounts if compromise is suspected.

Validation and detection

  • Inventory WordPress sites and identify every installed TrueBooker version.
  • Confirm no instance runs a TrueBooker release earlier than 1.2.4.
  • Verify the vulnerable front-end password-reset handler is no longer exposed or accepts unauthorized changes.
  • Review account, password-reset, administrator, and site-change logs for unexpected activity.
  • Confirm legitimate administrators retain control and no unauthorized privileged accounts exist.
