CVE-2025-62528 · Severity: medium · CVSS 5.4 · Published 2025-10-20

Taguette, an open-source qualitative data analysis tool, is vulnerable to a security flaw where project members can inject malicious scripts into tag and document fields. When other users load the affected project, these scripts execute automatically in their browser, potentially allowing unauthorized access to project data or session hijacking. This risk is particularly relevant for collaborative research environments where multiple users share access to the same project.

## Technical details

A stored cross-site scripting (XSS) vulnerability exists in Taguette's handling of project metadata. The application fails to properly neutralize user-controllable input in the tag name, tag description, document name, and document description fields before rendering them in the web interface. An attacker with project member privileges (PR:L) can inject malicious JavaScript that executes when any user loads the project. The vulnerability is reachable over the network and does not require specific user interaction beyond the standard action of loading the project page. This issue is tracked as CWE-79 and was patched in version 1.5.0.
