Name of the Vulnerable Software and Affected Versions Wekan versions prior to 9.31

Description A logged-in board member can perform arbitrary file reads and cause a denial of service by inserting an attachment document through the '/attachments/insert' DDP method. The issue occurs because the server fails to perform a storage-root containment check when streaming the stored path via the FileStoreStrategyFilesystem.getReadStream() function in 'models/lib/fileStoreStrategy.js'. An attacker can exploit this by controlling the versions.original.path and versions.original.storage fields, potentially accessing special files such as '/dev/zero'.

Recommendations Update to version 9.31.
