How broadly exploitable is this vulnerability in Indico?

Exploitability depends on whether server-side LaTeX rendering is enabled and exposed to user-controlled input. If `XELATEX_PATH` is set and users can supply LaTeX content, the issue can be remotely exploitable through the web interface. If LaTeX rendering is disabled or fully isolated in a locked-down container, the risk is significantly reduced.

Does an attacker need authenticated access to exploit this?

In many deployments, only authenticated users can submit LaTeX content, so a valid account may be required. However, the precise requirement depends on how the site is configured and where LaTeX input is accepted. Any role or endpoint that can influence LaTeX-rendered fields becomes a potential entry point.

What is the safest general fix pattern?

The safest pattern is to avoid executing untrusted LaTeX on the main host altogether. This typically means either disabling server-side LaTeX rendering or delegating it to a strongly sandboxed environment (such as a dedicated container with minimal privileges and tightly controlled file-system access), while also applying strict validation to any remaining LaTeX input.
