Descrição
Mattermost Plugins versions <=1.1.5 fail to sanitize filenames received from federated peers before using them to construct export destination paths, which allows an administrator of a remote federated Mattermost server to write files to arbitrary locations within the target server-s filestore via a malicious filename delivered through the shared-channel attachment sync protocol.
