CVE-2025-66687Public exploitNetwork attack vector

Code execution via unsanitized RAR entry paths

Published Mar 16, 2026 · Updated Mar 16, 2026

Path traversal in Doom Launcher 3.8.1.0 allows remote attackers to execute code as the current user through a crafted RAR game file. The game-loading logic passes relative RAR entry paths from SevenZipSharp directly to the file system without path validation, allowing files to escape the temporary extraction directory. Exploitation requires a user to load the archive; writing a payload into the Windows Startup folder executes it at the next login with that user's privileges.
