GHSA-29xf-69gq-m9jx: Coder: User-admin role can reset owner account password

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: | Release line | Patched version | |---|---| | 2.34 | v2.34.2 | | 2.33 | v2.33.8 | | 2.32 | v2.32.7 | | 2.29 (ESR) | v2.29.17 | Workarounds Restrict the user-admin role to trusted administrators until upgrading.
