Summary

Void through 1.3.4 contains a path traversal vulnerability in the AI agent file-reading tools that allows network-adjacent attackers to read arbitrary host files outside the open workspace by injecting instructions into content the agent processes. Attackers can supply absolute paths or file:// URIs through the read_file, ls_dir, get_dir_tree, and search_* tools, which lack workspace confinement and bypass the approval gate, enabling silent exfiltration of sensitive files such as SSH private keys or cloud credentials via subsequent tool calls.
