CVE-2024-47888 Information

Description

Action Text brings rich text content and editing to Rails. Starting in version 6.0.0 and prior to versions 6.1.7.9 7.0.8.5 7.1.4.1 and 7.2.1.1 there is a possible ReDoS vulnerability in the plain_text_for_blockquote_node helper in Action Text. Carefully crafted text can cause the plain_text_for_blockquote_node helper to take an unexpected amount of time possibly resulting in a DoS vulnerability. All users running an affected release should either upgrade to versions 6.1.7.9 7.0.8.5 7.1.4.1 or 7.2.1.1 or apply the relevant patch immediately. As a workaround users can avoid calling plain_text_for_blockquote_node or upgrade to Ruby 3.2. Ruby 3.2 has mitigations for this problem so Rails applications using Ruby 3.2 or newer are unaffected. Rails 8.0.0.beta1 depends on Ruby 3.2 or greater so is unaffected.
