There was a problem hiding this comment.
Thank you, @hacdias!
I believe this library is a good place to protect a wide array of users (not just Kubo) from issues described in ipfs/specs#288.
Hopefully does not impact legitimate use cases:
- I was unable to think about a scenario where this additional validation would introduce regression, but we will also have Kubo 0.17-rc1 to confirm that.
- If there are any issues, we can always add
ipfs get --allow-unsafe-paths(similar toipfs dag put --allow-big-block).

See ipfs/kubo#9029 and the “Security” section added in IPIP-288 (ipfs/specs#288)
This will affect both
ipfs get [--archive], as well as the new gateway TAR download format./cc @lidel
