Arbitrary file read via unchecked workspace path
Published Aug 11, 2026 · Updated Aug 11, 2026
Path traversal in OpenBMB XAgent before 26f2b6e allows remote attackers to read arbitrary host files through the workspace file endpoint. The file handler joins the attacker-controlled file_name field to an interaction directory and opens the result without rejecting parent segments or verifying path containment. Self-registration without email verification or shipped default credentials satisfies the account gate, exposing application secrets, database credentials, and system files.
