Name of the Vulnerable Software and Affected Versions
ByteDance DeerFlow versions prior to commit 2176b2b
Description
An issue exists in bootstrap-mode custom-agent creation where the validation of the agent name is bypassed. This allows attackers to use absolute paths or traversal-style values as the agent name to influence directory creation and write files outside the intended custom-agent directory, which may lead to arbitrary file write on the system depending on filesystem permissions.
Recommendations
Update to commit 2176b2b or a newer version.
