Description Cathy Hu 2023-03-20 11:36:36 UTC 
CVE-2023-28120

There is a vulnerability in ActiveSupport if the new bytesplice method is called on a SafeBuffer with untrusted user input. ActiveSupport uses the SafeBuffer string subclass to tag strings as html_safe after they have been sanitized. When these strings are mutated, the tag should be removed to mark them as no longer being html_safe.
