      <title>GHSA-pj73-v5mw-pm9j — Possible XSS Security Vulnerability in SafeBuffer#bytesplice</title>
      <link>https://vulnerability.circl.lu/vuln/ghsa-pj73-v5mw-pm9j</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; RubyGems: activesupport&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;
&lt;p&gt;Versions Affected: All. Not affected: None Fixed Versions: 7.0.4.3, 6.1.7.3&lt;/p&gt;
&lt;p&gt;# Impact&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;
&lt;p&gt;Ruby 3.2 introduced a new bytesplice method which ActiveSupport did not yet understand to be a mutation.
Users on older versions of Ruby are likely unaffected.&lt;/p&gt;
&lt;p&gt;All users running an affected release and using bytesplice should either upgrade or use one of the workarounds immediately.&lt;/p&gt;
&lt;p&gt;# Workarounds&lt;/p&gt;
&lt;p&gt;Avoid calling bytesplice on a SafeBuffer (html_safe) string with untrusted user input.&lt;/p&gt;</description>
