Omnispace Agora vulnerabilities

Omnispace Agora Project before version 25.10 contains a file upload vulnerability that allows authenticated users, and under certain conditions also guest users, to upload files via the UploadTmpFile action.

Omnispace Agora Project before version 25.10 contains a directory traversal vulnerability that allows unauthenticated attackers to read files on the system via the misc controller and the ExternalGetFile action. Only files with an extension can be read.

Omnispace Agora Project before 26.10.0 contains a code injection vulnerability where unescaped, attacker-controlled values are written into the config.inc.php configuration file during installation through File::updateConfigFile() and DbInstall::dbControl(), combined with an SQL injection issue enabled by PDO::ATTR_EMULATE_PREPARES supporting stacked queries. Attackers can exploit the SQL injection to re-trigger the installer and inject arbitrary PHP code into config.inc.php, achieving unauthenticated remote code execution on the underlying system.
