Description
Omnispace Agora Project through 26.10.0 contains a broken access control vulnerability in which the isAutor() function in MdlObject.php grants accessRight=3 based solely on object authorship without verifying the user still belongs to the object's space. Attackers who were previously members and authored objects can retain unauthorized read access to space objects even after being removed from the space, leading to persistent information disclosure.
