+# Soundness issue: Input<R> can be misused to create data race to an object
+
+`Input<R>` implements `Send` without requiring `R: Send`.
+
+Affected versions of this crate allows users to send non-Send types to other threads,
+which can lead to undefined behavior such as data race and memory corruption.
+
+The flaw was corrected in the PR(https://github.com/petabi/eventio/pull/34) by adding `R: Send` bound to the `Send` impl of `Input<R>`.
