A flaw was found in the Special:log/rights page in MediaWiki. Messages related to group memberships (group-*-member) within includes/logging/RightsLogFormatter.php are susceptible to cross-site scripting (XSS) attacks due to inadequate escape handling. This issue could enable an attacker to execute malicious scripts within the affected page, posing a risk of unauthorized code execution or other malicious activities.
