Ruby on Rails: v7.0.4.1 Release

This is a security release. More information is available in our security announcements forum: https://discuss.rubyonrails.org/c/security-announcements/9

Active Support

• Avoid regex backtracking in Inflector.underscore

  [CVE-2023-22796]

Active Model

• No changes.

Active Record

• Make sanitize_as_sql_comment more strict

  Though this method was likely never meant to take user input, it was attempting sanitization. That sanitization could be bypassed with carefully crafted input.

  This commit makes the sanitization more robust by replacing any occurrances of "/" or "/" with "/ " or " /". It also performs a first pass to remove one surrounding comment to avoid compatibility issues for users relying on the existing removal.

  This also clarifies in the documentation of annotate that it should not be provided user input.

  [CVE-2023-22794]

• Added integer width check to PostgreSQL::Quoting

  Given a value outside the range for a 64bit signed integer type PostgreSQL will treat the column type as numeric. Comparing integer values against numeric values can result in a slow sequential scan.

  This behavior is configurable via ActiveRecord::Base.raise_int_wider_than_64bit which defaults to true.

  [CVE-2022-44566]
