Real-World Exposure

1 pkg affected
.NETSinGooCMS.Utility

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects NuGet packages — download data is not available via public APIs for these ecosystems.

Description

This affects all versions of package SinGooCMS.Utility. The socket client in the package can pass in the payload via the user-controllable input after it has been established, because this socket client transmission does not have the appropriate restrictions or type bindings for the BinaryFormatter.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for SinGooCMS.Utility, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of SinGooCMS.Utility for CVE-2022-0749. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    Do not deserialise data from untrusted sources: where the format allows it, restrict deserialisation to an explicit allowlist of expected types, and prefer a data-only format (JSON, Protobuf) over one that can reconstruct arbitrary objects until you can upgrade.
