cdo-local-uuid project provides a specialized UUID-generating function that can, on user request, cause a program to generate deterministic UUIDs. An information leakage vulnerability is present in `cdo-local-uuid` at version `0.4.0`, and in `case-utils` in unpatched versions (matching the pattern `0.x.0`) at and since `0.5.0`, before `0.15.0`. The vulnerability stems from a Python function, `cdo_local_uuid.local_uuid()`, and its original implementation `case_utils.local_uuid()`.

The d8s-uuids for python, as distributed on PyPI, included a potential code-execution backdoor inserted by a third party. The backdoor is the democritus-hypothesis package. The affected version is 0.1.0

A flaw was found in github.com/satori/go.uuid in versions from commit 0ef6afb2f6cdd6cdaeee3885a95099c63f18fc8c to d91630c8510268e75203009fe7daf2b8e1d60c45. Due to insecure randomness in the g.rand.Read function the generated UUIDs are predictable for an attacker.

node-uuid before 1.4.4 uses insufficiently random data to create a GUID, which could make it easier for attackers to have unspecified impact via brute force guessing.

mysql-binuuid-rails 1.1.0 and earlier allows SQL Injection because it removes default string escaping for affected database columns.
