Executive Summary

This is a Cross-Site Scripting (XSS) vulnerability in pdfme schemas versions before 5.5.10. It occurs in the multiVariableText property panel where unsanitized i18n label values are assigned to innerHTML without proper neutralization. Attackers can inject arbitrary JavaScript by controlling label overrides through options.labels. The malicious code executes when users open the Designer and select a multiVariableText field without variable placeholders.

Detection Guidance

To detect this vulnerability, check the version of the @pdfme/schemas package in your project. If you are using version 5.5.9 or below, your system is vulnerable. Run commands like 'npm list @pdfme/schemas' or 'yarn list @pdfme/schemas' to verify the installed version.

Impact Analysis

This vulnerability could allow attackers to execute arbitrary JavaScript in your browser when you interact with a vulnerable pdfme Designer. This may lead to session hijacking, DOM manipulation, or stored XSS in multi-tenant applications. The impact is limited as it requires user interaction and the attacker must control label overrides.

Mitigation Strategies

Immediately update the @pdfme/schemas package to version 5.5.10 or later. If updating is not possible, review and sanitize all label values passed through options.labels to prevent XSS attacks. Remove any untrusted user-controlled label overrides.
