"The version of Coder installed on the remote host is prior to 2.29.17, 2.32.7, 2.33.8, or 2.34.2. It is,
therefore, affected by multiple vulnerabilities:

  - A user-admin role can reset the owner account password, resulting in privilege escalation from
    user-admin to owner. (CVE-2026-55077)

  - A workspace app upsert allows cross-workspace agent rebinding via user-controlled app ID,
    enabling traffic interception. (CVE-2026-55429)

  - The coder config-ssh command wrote server-supplied SSH settings into the user's SSH config without
    sanitizing embedded newlines, allowing arbitrary SSH configuration injection. (CVE-2026-55427)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
