Summary

In the OCI registry's cross-repository blob mount, the target package was checked against the token's `public-only` restriction, but the source blob was checked only against the token owner's full account permissions. A `public-only` token with `write:package` scope, whose owner can read a private package and write to a public package namespace, could mount a private package's blob into the public package, after which anyone could download it.

Risk Assessment

Confidential data such as container layers from a private package may leak into a publicly accessible package and be downloaded by unauthorized parties.

Recommendation

Update the OCI registry to a version containing the fix and review public packages for unexpected blobs originating from private repositories.

Original NVD description (English source)

The OCI registry's cross-repository blob mount checked the target package against the token's `public-only` restriction, but checked the source blob only against the full account permissions of the token owner. A `public-only` token with `write:package` scope, whose owner can read a private package and write to a public package namespace, could mount a blob of the private package into the public package. The private blob, such as a container layer, could then be downloaded by anyone through the public package.
