Booktics SQL Injection Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.3)

CVE-2026-109894

The vulnerability affects a WordPress plugin, which is typically deployed as part of an internet-facing web application. Since web applications are commonly accessed over the public internet to provide services to users, the underlying plugin code is frequently exposed to external network traffic.

SQL Injection

Halo Surface Signal: 4 out of 5 — likely to be public-facing.

Horizon Alert

Summary of the vulnerability and why it matters

This advisory highlights a critical SQL injection vulnerability found in the Booktics plugin for WordPress. If exploited, this flaw could allow an attacker to manipulate database queries, potentially leading to unauthorized access to or corruption of sensitive information. The primary concern is to confirm if this plugin is in use and to assess any potential exposure.

  • Attackers can inject malicious SQL commands.
  • Essential to verify if Booktics is used internally.
  • Confirm relevance and assess potential exposure.

Attack Path

How an attacker could exploit the issue

An attacker can exploit this vulnerability by sending specially crafted input to a Booktics application that is exposed to the internet. If the application does not properly sanitize this input before using it in an SQL query, the attacker's input can be executed as SQL commands. This could allow an attacker to access or manipulate sensitive data within the application's database.

  • Exposed to the internet without authentication.
  • Malicious input submitted to the application.
  • Unauthorized access to sensitive data.

Live Threat

Current exploitation, exposure, and threat context

This SQL injection vulnerability in Booktics could allow an unauthenticated attacker to access or manipulate sensitive data stored within the Booktics database when accessed through an affected system. The attacker could potentially read confidential information or disrupt the availability of Booktics services.

  • Database records and sensitive data.
  • Via network requests to the Booktics application.
  • Unauthorized data access or service disruption.

Operational Fix

Recommended remediation, mitigation, and detection steps

This SQL Injection vulnerability in Booktics impacts customer data and requires immediate attention from teams managing web applications and their associated plugins. The first step involves identifying all instances of Booktics across the environment, assessing their exposure to external networks, and confirming business criticality to prioritize remediation efforts with the accountable system owners.

  • Application and platform teams own the issue.
  • Verify Booktics installation and network exposure.
  • Plan coordinated vendor and owner remediation.

Frequently asked questions

What is the Booktics plugin for WordPress?

Booktics is a software plugin designed for WordPress sites to manage appointment scheduling and booking services. It functions as an extension that handles customer interactions and calendar management directly within a web environment.

How does this SQL injection vulnerability work in CVE-2026-109894?

This flaw belongs to the CWE-89 weakness class, meaning the plugin fails to properly filter malicious characters from user input. Because the software incorporates this uncleaned data directly into database commands, an attacker can manipulate those queries to interact with the underlying database in unauthorized ways.

Do I need to be authenticated for an attacker to trigger this bug?

No. The vulnerability does not require the attacker to have an existing account or administrative credentials. It is triggered by sending specially crafted network requests to the plugin; however, the bug is not triggered by standard, legitimate user interactions that follow the application's intended input patterns.

Is my site at higher risk if it is internet-facing?

Yes. According to Halo Surface Signal, because Booktics is a WordPress plugin typically used in web applications that must be accessible to the public, it is frequently exposed to external network traffic. This direct reachability from the internet increases the likelihood that an attacker can reach the vulnerable code.

What should I do first to address this CVE?

Begin by auditing your environment to locate every instance where the Booktics plugin is installed. Once identified, work with the system owners to determine which sites are reachable from the public internet versus those on internal networks, then prioritize remediation based on that accessibility.
