Ideally, we would restrict ImageMagick to only accessing its own
|
|
disk-backed pixel cache as well as Mastodon-created Tempfiles.
|
|
|
|
However, those paths depend on the operating system and environment
|
|
variables, so they can only be known at runtime.
|
|
|
|
Furthermore, those paths are not necessarily shared across Mastodon
|
|
processes, so even creating a policy.xml at runtime is impractical.
|
|
|
|
For the time being, only disable indirect reads.
