+# Exposes reference to non-Sync data to an arbitrary thread
+
+Affected versions do not enforce a `Sync` bound on the type of caller-provided
+value held in the plugin registry. References to these values are made
+accessible to arbitrary threads other than the one that constructed them.
+
+A caller could use this flaw to submit thread-unsafe data into inventory, then
+access it as a reference simultaneously from multiple threads.
+
+The flaw was corrected by enforcing that data submitted by the caller into
+inventory is `Sync`.
