Cross-Site Scripting (XSS) in CTI-Transmute (CVE-2026-71502)
Summary
Cross-site scripting in CTI-Transmute (CVE-2026-71502). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
CTI-Transmute contains a stored cross-site scripting vulnerability caused by insufficient neutralization of Vue template expression delimiters in server-rendered user-controlled data.
An unauthenticated attacker can create a public conversion whose name or description contains a malicious Vue expression using the application's configured [[ ... ]] delimiters. User profile names may provide an additional injection vector. Although Jinja HTML escaping is applied, the resulting value is subsequently included in a DOM region compiled by Vue.
Vue interprets the attacker-controlled value as a template expression rather than ordinary text. By accessing the JavaScript Function constructor from within the expression, an attacker can execute arbitrary JavaScript in the security context of the CTI-Transmute origin. The application's nonce-based Content Security Policy does not prevent exploitation because the Vue runtime compiler requires the unsafe-eval policy exception.
The malicious payload is stored by the application and executed whenever another user opens an affected page, such as the public conversion detail page. The victim may be a normal user or an administrator. Successful exploitation could allow the attacker to:
- Access data available to the victim through the application.
- Extract API keys, tokens, or other sensitive information exposed to the page.
- Perform authenticated actions using the victim's session.
- Modify conversions or other application data…
