CVE-2022-35956: Update By Case Project Update By Case

Critical severity, CVSS 9.8. EPSS: 0.6% chance of exploitation in the next 30 days.

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.
