Alert meAnalysisAIv1 – Jul 27, 2026
Privilege escalation via password reset in Coder allows a user-admin to reset any owner's password without knowing the current password, gaining full deployment control including templates, workspaces, and the ability to self-assign the owner role. This flaw affects Coder versions 2.34.0 to 2.34.1, 2.33.0 to 2.33.7, 2.30.0 to 2.32.6, and all prior to 2.29.17. Exploitation requires the user-admin role, limiting practical risk to deployments where less trusted operators are granted that role.

Network API abuse (AV:N/AC:L/UI:N) that requires the privileged user-admin role (PR:H); resulting owner takeover yields full C:H/I:H/A:H within one system (S:U).

DescriptionCVE.org
Summary
The PUT /api/v2/users/{user}/password endpoint authorized only ActionUpdatePersonal and did not prevent a user-admin from resetting an owner account's password. It also did not require the current password when an admin reset another user's password.
> Note: Exploitation requires the privileged user-admin role so practical risk is limited to deployments that grant user-admin to less trusted operators.
Impact
A user-admin could reset any owner's password without knowing it, authenticate as that owner and gain full deployment control, including templates, workspaces, licensing, organization settings and the ability to self-assign the owner role. This was a privilege escalation from user-admin to owner.
Patches
The fix prevents non-owner users from resetting the password of an account that holds the owner role.
The fix was backported to all supported release lines:
Workarounds
Restrict the user-admin role to trusted administrators until upgrading.

- Fix: #25709

Attack Technique
Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.
Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
