Echo: github.com/openfga/openfga: security update to 1.18.1

medium Tenable Self-Hosted Container Security Plugin ID 462522

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - OpenFGA is an authorization and permission engine built for developers. Prior to 1.18.1, the ListUsers API
 could return a user that should have been excluded when an authorization relation used an intersection
 containing a base but not excluded operand, the base was granted through a type-bound public wildcard, and
 the excluded user also had a concrete tuple through another intersection operand. In
 pkg/server/commands/listusers/list_users_rpc.go, expandIntersection counted the concrete tuple and
 wildcard without first rejecting entries in excludedUsersMap. Applications that used ListUsers to
 enumerate or enforce access could therefore treat an excluded user as authorized. This issue is fixed in
 version 1.18.1. (CVE-2026-61709)

Solution

Update the github.com/openfga/openfga library and its related packages to version 1.18.1 or later.
