wandb is vulnerable to Use of a Broken or Risky Cryptographic Algorithm
23
Low Risk
This Affects:
wandbTL;DR
ArtifactManifestEntry.download in wandb/sdk/lib/hashutil.py verifies downloaded artifact content against a manifest digest computed with a weak hash algorithm. A collision against that weak hash lets a downloaded file differ from what the manifest claims without the integrity check catching it. Exploiting this requires the ability to influence the artifact manifest or storage backend and is difficult to carry out reliably. The fix addresses the check by moving to a stronger hash.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
Background info
