+    title: 'Use-after-free in MessagePort::Entangled'
+    impact: high
+    reporter: Yangkang of 360 ATA Team
+    description: |
+      It was possible to cause the use of a MessagePort after it had already

+  CVE-2023-6206:
+    title: Clickjacking permission prompts using the fullscreen transition
+    impact: high
+    reporter: Hafiizh
+    description: |
+      The black fade animation when exiting fullscreen is roughly
+      the length of the anti-clickjacking delay on permission prompts.
+      It was possible to use this fact to surprise users by luring them
+      to click where the permission grant button would be about to appear.

+  CVE-2023-6207:

+    title: Using Selection API would copy contents into X11 primary selection.
+    impact: moderate
+    reporter: turistu
+    description: |
+      When using X11, text selected by the page using the Selection API was erroneously copied into the primary selection, a temporary storage not unlike the clipboard.<br>*This bug only affects Thunderbird on X11. Other systems are unaffected.*

+  CVE-2023-6209:
+    title: Incorrect parsing of relative URLs starting with "///"
+    impact: moderate
+    reporter: Rachmat Abdul Rokhim
+    description: |
+      Relative URLs starting with three slashes were incorrectly parsed, and a
+      path-traversal "/../" part in the path could be used to override the
+      specified host. This could contribute to security problems in web sites.

+    impact: high
+    reporter: Mozilla Developers
+    description: |
+      Memory safety bugs present in Firefox 119, Firefox 115.4, and Thunderbird 115.4. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.
