[2] *   Host nation ( Climbing Federation of Russia)On 18 September, the IFSC issued an apology after broadcasters showed a close-up of chalk handprints on Austrian climber Joanna Färber's bottom during the women's bouldering semi-finals in the event live feed.

The federation removed the feed from its YouTube channel and re-uploaded an edited video without the footage it described as "objectification of the human body."

This incident marked the second time in the season that the IFSC apologised for sexualised imagery, after a similar footage of Färber appeared on the live feed of the Innsbruck World Cup in June 2021.
