Omnispace Agora Project through 26.10.0 contains a SQL injection vulnerability that allows authenticated general administrators to inject arbitrary SQL by setting the personsSort session value, which is concatenated unsanitized into ORDER BY clauses in MdlUser.php and MdlSpace.php. Attackers can submit an error-based extractvalue payload through personsSort to leak database information, such as the MariaDB version, via the user and space listing pages.
