+I've reviewed this plugin's code, and there is one major issue with it,
+namely this line:
+
+ system("hnb '$params{page}.hnb' 'go root' 'export_html $tmp' > /dev/null");
+
+This could potentially allow execution of artibtary shell code, if the filename
+contains a single quote.
+
+* Fixed with version 0.02 by usage of `$params{content}` -- XTaran
+
+Which ikiwiki doesn't allow by default, but I prefer to never involve a shell where one is not needed. The otl plugin is a good example of how to safely fork a child process without involving the shell.
+
+* Had a look at that one as example before writing the hnb plugin, but hnb has different input/output characteristics. I would prefer another solution, too, but as long as it works and is secure, I'm fine with the current (fixed :-) ) solution -- [[XTaran]].
+
+Other problems:
+
+* Use of shell mktemp from perl is suboptimal. File::Temp would be better.
+ * Fixed with version 0.02 -- [[XTaran]]
+* The htmlize hook should not operate on the contents of `$params{page}.hnb`.
+ The content that needs to be htmlized is passed in to the hook in
+ `$params{content}`.
+ * Fixed with version 0.02 -- [[XTaran]]
+
+If these problems are resolved and a copyright statement is added to the file,
+
+* Copyright Statement is in their for about a month. -- [[XTaran]]
+
+I'd be willing to include this plugin in ikiwiki. --[[Joey]]
