No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

OpenBMB XAgent v1.0.0 and before is vulnerable to path traversal in the file() function in XAgent/XAgentServer/application/routers/workspace.py. The input parameter “filename” is user-controllable and is concatenated into the file path to be read without proper validation, leading to a directory traversal vulnerability that may result in sensitive information disclosure.
