CVE-2026-72743 in SQLBot
Summary
by MITRE • 08/11/2026
SQLBot through 1.10.0, fixed in commit c3f40a5, contains a stored cross-site scripting vulnerability in the SQText dashboard component that renders TinyMCE output via v-html without sanitization. Attackers who can modify dashboard text widget content can inject arbitrary HTML and JavaScript that executes for all users viewing the dashboard.

The SQLBot vulnerability represents a critical stored cross-site scripting flaw that exists within the SQText dashboard component of versions through 1.10.0. This vulnerability stems from improper input sanitization practices where the application renders TinyMCE output directly through v-html binding without any validation or sanitization measures. The security issue manifests when attackers gain the ability to modify content within dashboard text widgets, enabling them to inject malicious HTML and JavaScript code that persists in the application's database. When other users subsequently view the affected dashboard, their browsers execute the injected scripts in the context of the vulnerable application, creating a persistent threat vector.
The technical implementation of this vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws, and demonstrates how improper handling of untrusted data can lead to severe security consequences. The use of v-html binding without sanitization creates an environment where attacker-controlled content bypasses the application's security controls entirely. This particular flaw operates at the presentation layer where user-generated content should be strictly validated and sanitized before rendering, but instead allows direct HTML injection that executes with the privileges of the vulnerable application.
The operational impact of this vulnerability extends far beyond simple data theft or defacement. Attackers can leverage this stored XSS to perform session hijacking, steal cookies, redirect users to malicious sites, or even execute more sophisticated attacks such as credential harvesting. Since all users who view the dashboard are potentially affected, the scope of exploitation is broad and persistent, making it particularly dangerous for environments where dashboards serve as central monitoring interfaces. The vulnerability essentially transforms the dashboard into a command and control channel that can be used to compromise multiple user sessions simultaneously.
Mitigation strategies should focus on implementing proper input sanitization and output encoding mechanisms throughout the application. All user-generated content must undergo strict validation using established libraries such as DOMPurify or similar HTML sanitizers before being rendered in the browser context. The v-html binding should be replaced with safer alternatives that automatically sanitize content, or explicit sanitization steps should be implemented prior to content rendering. Additionally, access controls for dashboard modification should be strengthened through role-based permissions and input validation to prevent unauthorized users from injecting malicious content. Regular security audits and code reviews focusing on data handling practices will help identify similar vulnerabilities in other parts of the application that may present similar risks. The fix implemented in commit c3f40a5 demonstrates the importance of proper content sanitization and highlights how simple oversights in input handling can create persistent security threats that affect all users of the vulnerable system.
