CVE-2026-25559Public exploitNetwork attack vector

Authenticated code execution via absolute wordlist paths

Published Jun 8, 2026 · Updated Jun 8, 2026

Path traversal in OpenBullet 2 0.3.2 and earlier allows remote authenticated users to read, write, and delete arbitrary host files. The wordlist upload handler passes an absolute file.FileName to Path.Combine, which discards the intended Wordlists base directory; related load, preview, and delete routes then operate on the attacker-chosen path. Administrative access is required, and default root execution makes SSH-key or account-file manipulation sufficient for host code execution.
