patch available.

  - 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. (CVE-2026-65698)

Note that Nessus relies on the presence of the package as reported by the vendor.");
