Overview
wandb is an A CLI and library for interacting with the Weights and Biases API.
Affected versions of this package are vulnerable to Use of Weak Hash through ArtifactManifestEntry.download in wandb/sdk/artifacts/artifact_manifest_entry.py and related artifact verification paths. An attacker can bypass or poison artifact integrity checks by supplying content that collides under the MD5-based digest comparison used for cached downloads and local file verification. This allows a substituted artifact file to be accepted as legitimate during download or verification, so users may load, cache, or verify tampered artifact contents instead of the expected file.
