CVSS 2.x

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 product inserts sensitive information into debugging code, which could expose this information if the debugging code is not disabled in production.

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
