Teams running Omnispace Agora Project through 26.10.0 where users are removed from spaces that still hold objects they authored. The flaw is in the access check in MdlObject.php, so exposure depends on that code path being reached; the sources do not say which deployments are most exposed.

Unknown from the sources.
No fix yet, per the sources.
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.
