> # RubyGem omniauth-facebook access token security vulnerability
> There is a security vulnerability in the omniauth-facebook <= 1.5.0.
>     Versions affected: <= 1.5.0
>     Fixed versions:    >= 1.5.1
> ## Impact
> Because omniauth-facebook <= 1.5.0 supports passing an access token
> directly in the URL, an attacker may be able to authenticate as
> another user by passing a valid access token obtained from Facebook
> for another app.
> If you're currently using this feature, and passing the access token
> directly, you should change your integration to use one of the secure
> methods using either a signed request or the code flow. These secure
> methods are default, so unless you are explicitly passing an access
> token you should not need to make any integration changes to upgrade
> to 1.5.1.
> All users running an affected release should upgrade to >= 1.5.1.
> ## Releases
> The 1.5.1 releases is available at the normal locations.
> ## Workarounds
> None.
