After the Christmas break, Gössner claimed her second World Cup win in the Oberhof sprint race. She also came third with the German relay team in the Oberhof women's relay. One week later, she won her second sprint race in a row in Ruhpolding. At the last World Cup stage before the world championships, Gössner missed seven out of ten targets in the Antholz sprint, finishing in 62nd place. It was the second worst result of her career, which also meant she failed to qualify for the subsequent pursuit. However, two days later in the last event before the 2013 Biathlon World Championships she was part of Germany's winning relay team. At the Biathlon Worlds themselves, she failed to secure a medal, with her best finishes being a pair of sixth places in the sprint and the mass start. Subsequently, she also narrowly missed out on a medal at the 2013 Nordic Worlds in Val di Fiemme, her first cross-country appearance since the 2010 Olympics, where she finished fourth in the 10km freestyle, half a second behind bronze medallist Yuliya Chekalyova.
