Originally Paseka was not chosen to compete in the 2015 European Artistic Gymnastics Championships held in Montpellier, France. However, due to the injuries of Alla Sosnitskaya, Paseka was decided to be the last minute replacement for her. Paseka arrived in Montpellier after the podium training, so she started the competition without it. Nevertheless, she qualified with 14.416, the fourth highest score, into the vault final, competing a Cheng vault with a difficulty score of 6.4 as her first vault and an Amanar with a 6.3 difficulty score as her second vault. She also gained a score which would have allowed her to enter the uneven bars final (14.233); however, she gave up her place due to the two per country rule. In the vault final held on 18 April, Paseka won the gold medal with a score 15.250. This was her first European vault medal. With the victory, she defeated the defending 2-time European vault champion Giulia Steingruber.
