Impact The savereport tool in openchatbi/tool/savereport.py suffers from a critical path traversal vulnerability due to insufficient input sanitization of the fileformat parameter.

The function only removes leading dots of fileformat using fileformat.lstrip(".") but allows path traversal sequences like /../../ to pass through unchanged. When the filename is constructed via string concatenation in

f"{timestamp}{cleantitle}.{fileformat}"

malicious path sequences are preserved, enabling attackers to write files outside the designated report directory.

An attacker can manipulate the LLM to call the tool with a specific fileformat to overwrite critical system files like init.py, potentially leading to remote code execution.

Patches - Affected versions: <=0.2.1 - Patched versions: 0.2.2 (includes fix from PR #12: https://github.com/zhongyu09/openchatbi/pull/12)

Workarounds No

A security flaw has been discovered in zhongyu09 OpenChatBI up to 0.3.0. Affected by this vulnerability is the function validatesqlsafety of the file openchatbi/text2sql/generatesql.py. Performing a manipulation results in sql injection. The attack can be initiated remotely. Versions v0.2.0 through v0.2.2 have no SQL safety validation at all, while v0.3.0 introduced a validator and v1.0.0b1/main kept the same incomplete one with an optional stricter mode. The vendor was contacted early about this disclosure but did not respond in any way.
