Vulnerability Title
Indico discloses local files resulting in Remote Code Execution through LaTeX injection
Vulnerability Description
Indico is an event management system that uses Flask-Multipass, a multi-backend authentication system for Flask. In versions prior to 3.3.12, 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. Note that if server-side LaTeX rendering is not in use (ie `XELATEX_PATH` was not set in `indico.conf`), this vulnerability does not apply. It is recommended to update to Indico 3.3.12 as soon as possible. It is also strongly recommended to enable the containerized LaTeX renderer (using `podman`), which isolates it from the rest of the system. As a workaround, 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.

Vulnerability Title
Indico 操作系统命令注入漏洞
Vulnerability Description
Indico是Indico开源的一个功能丰富的事件管理系统。 Indico 3.3.12之前版本存在操作系统命令注入漏洞，该漏洞源于TeXLive漏洞和可绕过LaTeX清理器的模糊LaTeX语法，可能导致使用特制LaTeX片段读取本地文件或以服务器上运行Indico的用户权限执行代码。
