PatchTheCVECVE-2022-35956: This Rails gem adds two methods to the ActiveRecord::Base class that allow you to update many records on a sin
CVE-2022-35956 is a medium-severity flaw (CVSS 5.8) affecting update by case. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
This Rails gem adds two methods to the ActiveRecord::Base class that allow you to update many records on a single database hit, using a case sql statement for it. Before version 0.1.3 `update_by_case` gem used custom sql strings, and it was not sanitized, making it vulnerable to sql injection. Upgrade to version >= 0.1.3 that uses `Arel` instead to construct the resulting sql statement, with sanitized sql.
Why this priority
- No elevated risk signals yet
A fixed release or distro patch exists.
