Summary
Snipe-IT's S3 signature image retrieval lacks authorization before temporary URL
Details

Impact

Snipe-IT S3 signature image retrieval lacks authorization before temporary URL.

On S3-backed deployments, authenticated users who know a signature filename can obtain a 5-minute signed S3 URL because the S3 branch returns before the authorize() call used by the local-file branch.
