An issue was discovered in the SportsTeams extension for MediaWiki before 1.35.12, 1.36.x through 1.39.x before 1.39.5, and 1.40.x before 1.40.1. SportsTeams: Special:SportsManagerLogo and Special:SportsTeamsManagerLogo do not check for the sportsteamsmanager user right, and thus an attacker may be able to affect pages that are concerned with sports teams.
