Details
There is a possible information disclosure / unintended method execution vulnerability in Action Pack which has been assigned the CVE identifier CVE-2021-22885. Versions Affected: >= 2.0.0. Not affected: < 2.0.0. Fixed Versions: 6.1.3.2, 6.0.3.7, 5.2.4.6, 5.2.6 Impact ------ There is a possible information disclosure / unintended method execution vulnerability in Action Pack when using the `redirect_to` or `polymorphic_url` helper with untrusted user input. Vulnerable code will look like this: ``` redirect_to(params[:some_param]) ``` All users running an affected release should either upgrade or use one of the workarounds immediately. Workarounds ----------- To work around this problem, it is recommended to use an allow list for valid parameters passed from the user. For example: ``` private def check(param) case param when "valid" param else "/" end end def index redirect_to(check(params[:some_param])) end ``` Or force the user input to be cast to a string like this: ``` def index redirect_to(params[:some_param].to_s) end ```
