Hi list, To rgod: it would have been *very* nice to contact us before posting this here... The problem has been confirmed from release 0.9.9 up to 0.9.12-rc1, the final 0.9.12 (which came out yesterday night) does fix the problem (+ another one of the same type introcuced in the 0.9.12 branch which was found while auditing the code after the initial security hole had been revealed). All phpGraphy users are *HIGHLY* encouraged to upgrade to the latest stable release -> 0.9.12 All apologies for this, we do take security very seriously and try our best to keep phpGraphy as secure as possible.
