multicast in source builds from vulnerable setuptools dependency
Impact
- Some source-builds may be impacted by a CWE-1395 (eg. vulnerable
setuptoolsdependency).- Multicast prior to v2.0.9a3 on systems with minimal dependancies installed may use
setuptools <78.1.1and 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.
- Multicast prior to v2.0.9a3 on systems with minimal dependancies installed may use
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.
