Is this vulnerability remotely exploitable?

Not directly over the network by itself. Exploitation typically requires convincing a user to open a crafted game archive or mod pack in Doom Launcher, but this can be facilitated via malicious downloads, mod repositories, or file sharing.

What level of access does an attacker need?

An attacker needs the ability to provide or influence the game archive that the victim imports into Doom Launcher. Once the victim processes the crafted archive, the vulnerable extraction logic can write files outside the intended directory.

What is the safest general fix pattern?

The safest fix pattern is to enforce strict path normalization and validation for all archive entries, rejecting any path that resolves outside a designated, restricted game content directory, and ignoring absolute or traversal-containing paths.
