CVE-2023-28120
GHSA-pj73-v5mw-pm9j
GMS-2023-765
Possible XSS Security Vulnerability in SafeBuffer#bytesplice There is a vulnerability in ActiveSupport if the new bytesplice method is called on a SafeBuffer with untrusted user input. This vulnerability has been assigned the CVE identifier CVE-2023-28120. Versions Affected: All. Not affected: None Fixed Versions: 7.0.4.3, 6.1.7.3 # Impact ActiveSupport uses the SafeBuffer string subclass to tag strings as html_safe after they have been sanitized. When these strings are mutated, the tag is should be removed to mark them as no longer being html_safe. Ruby 3.2 introduced a new bytesplice method which ActiveSupport does not yet understand to be a mutation. Users on older versions of Ruby are likely unaffected. All users running an affected release and using bytesplice should either upgrade or use one of the workarounds immediately. # Workarounds Avoid calling bytesplice on a SafeBuffer (html_safe) string with untrusted user input.

Direct Manipulation XSS Ruby on Rails contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate direct manipulations of `SafeBuffer` objects via `'[]'` and other methods. This may allow a user to create a specially crafted request that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
