Technical details

The /attachment/preview/{id} and /pic/preview/{id} endpoints are configured as anonymous in ShiroFilter and call AttachmentService.getResource, which performs only a bare primary-key lookup without checking ownership, organization membership, or permissions. An attacker can predict or discover file IDs (generated by IDGenerator.nextStr) and retrieve files belonging to other organizations. The fix in version 1.7.4 introduces a FileAccessAuthFilter to enforce proper authorization.
