GHSA-rfjc-xrmf-5vvw
Privilege escalation by backend users assigned to the default "Publisher" system role
Quick fix
GHSA-rfjc-xrmf-5vvw — october/backend: upgrade to the fixed version with the command below.
composer require october/backend:^1.0.470Details
### Impact Backend users with the default "Publisher" system role have access to create & manage users where they can choose which role the new user has. This means that a user with "Publisher" access has the ability to escalate their access to "Developer" access.
### Patches Issue has been patched in Build 470 (v1.0.470) & v1.1.1.
### Workarounds Apply https://github.com/octobercms/october/commit/78a37298a4ed4602b383522344a31e311402d829 to your installation manually if unable to upgrade to Build 470 or v1.1.1.
