# IBM i: authenticated user can gain QSECOFR security officer privileges

IBM i versions 7.3 through 7.6 let a logged-in user raise their privileges. An attacker who exploits it can act with QSECOFR (security officer) authority on the system.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

IBM i 7.3, 7.4, 7.5, and 7.6 is vulnerable to an authenticated attacker elevating their privilege. A bad actor could exploit this vulnerability to perform operations with QSECOFR/Root authority on the system.
