Stefan Esser reports:

During the evaluation of DokuWiki for a german/korean wiki of mine a flaw in DokuWiki's spellchecker was discovered, that allows injecting arbitrary PHP commands, by requesting a spellcheck on PHP commands in 'complex curly syntax'.

Because the spellchecker is written as part of the AJAX functionality of DokuWiki, it can be directly called by any website visitor, without the need for a wiki account.
