# Duplicate Advisory: Active Storage: Possible arbitrary file write and read in Active Storage image analysis

Link for people: https://infrastack.ai/live/GHSA-wgv4-95jc-33jm (this .md is for agents)

This advisory is withdrawn as a duplicate of GHSA-f3w6-w445-fwh9, so the live record is that one. The original text says Active Storage's ImageMagick analyzer, run when a file is attached, can let an attacker read and write files on the server, such as reading secret_key_base.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- rubygems:activestorage affected < 8.0.5.2 fixed no fixed version listed

## How to check

- Run `bundle exec rails -v` or check the `activestorage` version in `Gemfile.lock`
- Check whether the app uses Active Storage image analysis with ImageMagick (`config.active_storage.variant_processor` set to `:mini_magick`)
- Follow the live advisory GHSA-f3w6-w445-fwh9 for the affected range

## From the sources

## Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-f3w6-w445-fwh9. This link is maintained to preserve external references.

## Original Description
The activestorage gem before 8.1.4.1 for Ruby on Rails, when ImageMagick attachment processing occurs, can allow server read and write operations (e.g., reading secret_key_base) because the ImageMagick analyzer runs when a file is attached, and there is not an ImageMagick security policy to block unintended functionality.
