Vulnerability from github – Published: 2019-09-27 20:01 – Updated: 2023-08-29 11:51

Summary

Consul gem insufficient authentication check - Multiple powers in one controller are not always checked correctly

Details

With the consul ruby gem before 1.0.3, if a controller checks multiple powers using :if or :except conditions, these conditions are erroneously applied to all power checks in that controller. This can lead to skipped power checks and hence unauthenticated access to certain controller actions.

Severity ?

9.8 (Critical)
