AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
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).

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.

AnalysisAI
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.
