Dromara free-fs 2.0.1 through 2.3.1 contains an authorization bypass vulnerability that allows attackers to access code-protected shares because share codes are enforced only client-side. Attackers knowing a share ID can call the share items and download endpoints to list and download files without the code, even on preview-only shares.
