At the 2012 World Championships in Ruhpolding, Gössner managed to end the season with a good performance in front of her home fans. Despite mixed results, she was selected to run the third leg of Germany's women's relay, alongside Tina Bachmann, Magdalena Neuner and Andrea Henkel. She used three spare rounds and led the team from third to first position, playing a pivotal part in Germany's eventual relay victory.
