Is this vulnerability remotely exploitable?

Yes. Because the `/api.php` tex2png endpoint can be reached over HTTP and does not require authentication, an attacker with network access to the service can exploit it remotely by sending crafted LaTeX payloads.

What level of access does an attacker need to exploit this issue?

The attacker only needs the ability to connect to the exposed Tea LaTeX API endpoint. No valid user account or prior foothold on the server is required, making this a high-risk, unauthenticated attack surface.

What is the safest general fix pattern for this vulnerability class?

The most robust fix is to eliminate shell-based command construction using user-controlled data altogether. Invoke LaTeX and related tools through APIs that supply arguments as structured parameters rather than strings, apply strict input validation and feature restrictions to LaTeX content, and run the rendering process inside a hardened sandbox with least privileges.
