+        <p>Multiple vulnerabilities have been discovered in Ruby on Rails. Please review the CVE identifiers referenced below for details.</p>
+    </description>
+    <impact type="normal">
+        <p>When serialized columns that use YAML (the default) are deserialized, Rails uses YAML.unsafe_load to convert the YAML data in to Ruby objects. If an attacker can manipulate data in the database (via means like SQL injection), then it may be possible for the attacker to escalate to an RCE.

+

+Impacted Active Record models will look something like this:

+

+class User &lt; ApplicationRecord

+  serialize :options       # Vulnerable: Uses YAML for serialization

+  serialize :values, Array # Vulnerable: Uses YAML for serialization

+  serialize :values, JSON  # Not vulnerable

+end

+

+The released versions change the default YAML deserializer to use YAML.safe_load, which prevents deserialization of possibly dangerous objects. This may introduce backwards compatibility issues with existing data.</p>
+    </impact>
+    <workaround>
+        <p>There is no known workaround at this time.</p>
+    </workaround>
+    <resolution>
+        <p>All Ruby on Rails users should upgrade to the latest version:</p>
