### Impact In Kaminari before 1.2.1, there is a vulnerability that would allow an attacker to inject arbitrary code into pages with pagination links. This has been fixed in 1.2.1. ### Releases The 1.2.1 gem including the patch has already been released. All past released versions are affected by this vulnerability. ### Workarounds Application developers who can't update the gem can workaround by overriding the `PARAM_KEY_EXCEPT_LIST` constant. ```ruby module Kaminari::Helpers PARAM_KEY_EXCEPT_LIST = [:authenticity_token, :commit, :utf8, :_method, :script_name, :original_script_name].freeze end ``` ### Credits Thanks to Daniel Mircea for finding the issue and sending a patch via GitHub. Also thanks to Aditya Prakash for reporting the vulnerability.
