How to Fix CVE-2022-0329

To remediate this vulnerability, upgrade all affected Withdrawn dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

loguru fixed: 0.6.0 
pip install loguru>=0.6.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show loguru

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2022-0329, inspect your installed packages using pip:

pip show loguru

Analyze the terminal output to locate any version of Withdrawn in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.6.0), your application is affected.

Note: The pip show loguru command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Withdrawn, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

# Withdrawn This advisory has been withdrawn after the maintainers of loguru noted this issue is not a security vulnerability and the CVE has been revoked. We have [stopped](https://github.com/Delgan/loguru/issues/563#issuecomment-1025223732) Dependabot alerts regarding this issue. ## Original Description In versions of loguru up to and including 0.5.3 a lack of sanitization on log serialization can lead to arbitrary code execution. The maintainer disputes the issue, but has altered behavior of the library in commit 4b0070a4f30cbf6d5e12e6274b242b62ea11c81b. See https://github.com/Delgan/loguru/issues/563 for further discussion of the issue. The function in question is intended for internal use only, but is not restricted. This has been patched in version 0.6.0.
