Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Poweradmin versions 4.0.0 up to 4.2.5 and 4.3.0 up to 4.3.4 are affected. A user holding the user_edit_others permission, but not superuser status, can use the REST API user-update endpoint to change the password of the administrator account and then log in as that administrator, giving full control. Upgrade to 4.2.5 or 4.3.4. The source gives no workaround besides upgrading, and it notes that the attack requires the API to be enabled and a delegated user-manager role to exist.
