Upgrade github.com/openfga/openfga/pkg/server/commands/listusers to version 1.18.1 or higher.
Overview
Affected versions of this package are vulnerable to Incorrect Authorization in the ListUsers. An attacker can gain unauthorized access to information by exploiting an intersection of relations where a user excluded by a but not clause is also granted access through another operand.
Note: This is only exploitable if the authorization model contains a relation defined as an intersection (and) with at least one operand being an exclusion of the form base but not excluded, the base side of that exclusion is granted through a type-bound public wildcard, a user excluded by the but not clause is also granted via a concrete tuple through another operand of the intersection, and the application uses ListUsers to enumerate or enforce access.
