| Summary | Snipe-IT's S3 signature image retrieval lacks authorization before temporary URL ### 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. ## Key evidence `routes/web.php:135-143`; `app/Http/Controllers/ActionlogController.php:16-44`; `app/Http/Controllers/Account/AcceptanceController.php:160,175`; `app/Listeners/LogListener.php:56`; `app/Http/Transformers/ActionlogsTransformer.php:188` ### Patches Patched in https://github.com/grokability/snipe-it/commit/ded6515cbc27a28f07395da318483c2e96263259 ### Credit Disclosed by Ikaro tiagonas |
