Description
Impact
The annotation displayer does not execute the content in a restricted context. This allows executing anything with the right of the author of any document by annotating the document.
To reproduce: add an annotation with the content {{groovy}}print "hello"{{/groovy}} and click the yellow scare to get a display of the annotation inline.
The result is "hello" but it should be an error suggesting that it's not allowed to use the groovy macro.
Patches
This has been patched in XWiki 13.10.11, 14.4.7 and 14.10.
Workarounds
There is no easy workaround except to upgrade.
