Description Vincent Danen 2011-12-06 14:17:29 EST

It was reported [1],[2] that Apache MyFaces 2 would re-evaluate param/model values as EL expressions under certain conditions. If a submit outcome included both faces-redirect=true and includeViewParams=true (or faces-include-view-params=true), it would be possible to inject EL expressions directly into input fields mapped as view parameters.

This is fixed in upstream versions 2.0.11 and 2.1.5.  A patch [3] and reproducer [4] are available.
