+	  <h3>Overview</h3>
+	    <p>A maliciously crafted archive with "../" in the file paths
+		would install files anywhere in the user's home directory upon extraction.</p>
+
+	  <h3>Proof of concept</h3>
+	  <p>For testing, an example of malicious archive can be found at
+	      https://github.com/jwilk/traversal-archives/releases/download/0/relative2.zip</p>
+
+	  <h3>Impact</h3>
+	  <p>Users can unwillingly install files like a modified .bashrc, or a malicious
+	      script placed in ~/.config/autostart</p>
+
+	  <h3>Workaround</h3>
+	  <p>Users should not use the 'Extract' context menu from the Dolphin file manager.
+	    Before extracting a downloaded archive using the Ark GUI, users should inspect it
+	      to make sure it doesn't contain entries with "../" in the file path.</p>
+
+	  <h3>Solution</h3>
+	  <p>Ark 20.08.0 prevents loading of malicious archives and shows a warning message
+	    to the users.</p>
+
+	  <p>Alternatively,
+	    https://invent.kde.org/utilities/ark/-/commit/0df592524fed305d6fbe74ddf8a196bc9ffdb92f
+	      can be applied to previous releases.</p>
+
+	  <h3>Credits</h3>
+	  <p>Thanks to Dominik Penner for finding and reporting this issue and thanks to
+	    Elvis Angelaccio and Albert Astals Cid for fixing it.</p>
