+	<blockquote cite="https://matrix.org/blog/2021/09/13/vulnerability-disclosure-key-sharing">
+	  <p>Today we are disclosing a critical security issue affecting
+	  multiple Matrix clients and libraries including Element
+	  (Web/Desktop/Android), FluffyChat, Nheko, Cinny, and SchildiChat.</p>
+	  <p>Specifically, in certain circumstances it may be possible to
+	  trick vulnerable clients into disclosing encryption keys for
+	  messages previously sent by that client to user accounts later
+	  compromised by an attacker.</p>
+	  <p>Exploiting this vulnerability to read encrypted messages requires
+	  gaining control over the recipient’s account. This requires either
+	  compromising their credentials directly or compromising their homeserver.</p>
