CVE-2026-55077 (opens in a new tab)How to fix?
There is no fixed version for github.com/coder/coder/coderd.
Overview
Affected versions of this package are vulnerable to Improper Authorization via the PUT /api/v2/users/{user}/password endpoint. An attacker can gain unauthorized access to owner-level accounts by resetting their passwords without knowing the current password, allowing privilege escalation and full control over the deployment. This is only exploitable if the attacker holds the privileged user-admin role.
Workaround
This vulnerability can be mitigated by restricting the user-admin role to trusted administrators until upgrading.
