Description
Indico is an event management system that uses Flask-Multipass, a multi-backend authentication system for Flask. Prior to version 3.3.8, there is a Cross-Site-Scripting vulnerability when rendering LaTeX math code in contribution or abstract descriptions. Users should to update to Indico 3.3.8 as soon as possible. As a workaround, only let trustworthy users create content on Indico. Note that a conference doing a Call for Abstracts actively invites external speakers (who the organizers may not know and thus cannot fully trust) to submit content, hence the need to update to a a fixed version ASAP in particular when using such workflows.

Executive Summary

CVE-2025-59035 is a Cross-Site Scripting (XSS) vulnerability in the Indico event management system, specifically when rendering LaTeX math code in contribution or abstract descriptions. This flaw allows attackers to inject and execute malicious scripts in the web application because the system does not properly sanitize special characters in the LaTeX input. The vulnerability affects Indico versions up to 3.3.7 and is fixed in version 3.3.8. [1]

Impact Analysis

This vulnerability can lead to unauthorized script execution within the Indico web application, potentially causing limited unauthorized disclosure of information (confidentiality impact) and limited unauthorized modification of data (integrity impact). However, it does not affect system availability. Exploitation requires some user interaction and low privileges but can be performed remotely. [1]

Mitigation Strategies

Update Indico to version 3.3.8 or later where the vulnerability is patched. As a temporary workaround, restrict content creation to only trusted users, especially in workflows like Calls for Abstracts where external users may submit content. [1]
