Summary
multicast in source builds from vulnerable setuptools dependency
Details

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.
