## Overview

> [!NOTE]
> If server-side LaTeX rendering is not in use (ie `XELATEX_PATH` was not set in `indico.conf`), this vulnerability does not apply.

### Impact
Due to vulnerabilities in TeXLive and obscure LaTeX syntax that allowed circumventing Indico's LaTeX sanitizer, it is possible to use specially-crafted LaTeX snippets which can read local files or execute code with the privileges of the user running Indico on the server.

### Patches
It is recommended to update to [Indico 3.3.12](https://github.com/indico/indico/releases/tag/v3.3.12) as soon as possible.
See [the docs](https://docs.getindico.io/en/stable/installation/upgrade/) for instructions on how to update.

It is also strongly recommended to enable the containerized LaTeX renderer (using `podman`), which isolates it from the rest of the system. See [the docs](https://docs.getindico.io/en/stable/installation/upgrade/#upgrading-to-3-3-12) for details - it is very easy and from now on the only recommended/supported way of using LaTeX.

### Workarounds
Remove the `XELATEX_PATH` setting from `indico.conf` (or comment it out or set it to `None`) and restart the `indico-uwsgi` and `indico-celery` services to disable LaTeX functionality.
