+  CVE-2022-3033:
+    title: Leaking of sensitive information when composing a response to an HTML email with a META refresh tag
+    impact: high
+    reporter: Sarah Jamie Lewis
+    description: |
+      If a Thunderbird user replied to a crafted HTML email containing a <code>meta</code> tag, with the <code>meta</code> tag
+      having the <code>http-equiv="refresh"</code> attribute, and the content attribute specifying an URL, then
+      Thunderbird started a network request to that URL, regardless of the configuration to block
+      remote content. In combination with certain other HTML elements and attributes in the email,
+      it was possible to execute JavaScript code included in the message in the context of the
+      message compose document. 
+      The JavaScript code was able to perform actions including, but probably not limited
+      to, read and modify the contents of the message compose document, including the quoted
+      original message, which could potentially contain the decrypted plaintext of encrypted data 
+      in the crafted email.
+      The contents could then be transmitted to the network, either to the URL specified in the META refresh tag,
+      or to a different URL, as the JavaScript code could modify the URL specified in the document.
+      This bug doesn't affect users who have changed the default Message Body display setting to
+      'simple html' or 'plain text'.

+  CVE-2022-3032:
+    title: Remote content specified in an HTML document that was nested inside an iframe's srcdoc attribute was not blocked
+    impact: moderate
+    reporter: Sarah Jamie Lewis
+    description: |
+      When receiving an HTML email that contained an <code>iframe</code> element, which used a <code>srcdoc</code> attribute to define the inner HTML document, remote objects specified in the nested document, for example images or videos, were not blocked. Rather, the network was accessed, the objects were loaded and displayed.

+    title: Matrix SDK bundled with Thunderbird vulnerable to denial-of-service attack
+    impact: moderate
+    reporter: Val Lorentz
+    feed: false
+    description: |
+        Thunderbird users who use the Matrix chat protocol were vulnerable to a denial-of-service attack. An adversary sharing a room with a user had the ability to carry out an attack against affected clients, making it not show all of a user's rooms or spaces and/or causing minor temporary corruption.
