    multicast in source builds from vulnerable setuptools dependency

    GHSA-94v7-wxj6-r2q5

    Affected
    • PyPI multicast < 2.0.9a0
    Fixed in
    2.0.9a0· Vendor fix available
    Issue
    Impact Some source-builds may be impacted by a CWE-1395 (eg. vulnerable setuptools dependency). Multicast prior to v2.0.9a3 on systems with minimal dependancies installed may use setuptools <78.1.1 and thus rely on a compromised dependency. In some cases there is a chance that source-builds would fail due to an exploit of the closely related CVE-2025-47273, or become arbitrarily modified. Patches Pre-release version v2.0.9a0 and later resolve the issue by bumping requirements to setuptools=80.4 Pre-release version v2.0.9a3 and later are recommended for improved stability over v2.0.9a0 Workarounds Further hardening in v2.0.9a4+ of the build process in CI builds allowing source builds to be verified via GH attestations.

    Recommended action: Upgrade to 2.0.9a0 (pre-release) or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
