+security holes breed. It needs a test suite at the very least.

+
+# Probable non-holes
+
+## exploting ikiwiki with bad content
+
+Someone could add bad content to the wiki and hope to exploit ikiwiki.
+Note that ikiwiki runs with perl taint checks on, so this is unlikely.
+
+## publishing cgi scripts
+
+ikiwiki does not allow cgi scripts to be published as part of the wiki. Or
+rather, the script is published, but it's not marked executable, so
+hopefully your web server will not run it.
+
+## suid wrappers
+
+ikiwiki --wrapper is intended to generate a wrapper program that
+runs ikiwiki to update a given wiki. The wrapper can in turn be made suid,
+for example to be used in a [[post-commit]] hook by people who cannot write
+to the html pages, etc.
+
+If the wrapper script is made suid, then any bugs in this wrapper would be
+security holes. The wrapper is written as securely as I know how, is based on code that has a history of security use long before ikiwiki, and there's been no problem yet.
+
+## shell exploits
+
+ikiwiki does not expose untrusted data to the shell. In fact it doesn't use system() at all, and the only use of backticks is on data supplied by the wiki admin. And it runs with taint checks on of course..
