Coder < 2.29.17 / 2.30.x < 2.32.7 / 2.33.x < 2.33.8 / 2.34.x < 2.34.2 Multiple Vulnerabilities

high Nessus Plugin ID 326280

Synopsis

The remote host has an application installed that is affected by multiple vulnerabilities.

Description

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.

Solution

Update Coder to version 2.29.17, 2.32.7, 2.33.8, or 2.34.2 or later.
