CVE-2022-34981: 
Python vulnerability analysis and mitigation

The PyCrowdTangle package in PyPI before version 0.0.1 contained a code execution backdoor that was maliciously inserted by a third party. The vulnerability was discovered and disclosed on July 22, 2022, affecting versions 0.0.1~0.0.2 of the package. The malicious backdoor was implemented through a compromised 'request' package that, while removed from PyPI, remained available on various mirror sites (GitHub Issue).

The vulnerability has been assigned a CVSS v3.1 Base Score of 9.8 (Critical), indicating the highest severity level. The attack vector is Network-based, with low attack complexity, requiring no privileges or user interaction. The scope is unchanged, but the impact on confidentiality, integrity, and availability is rated as High (NVD).

The backdoor allowed unauthorized code execution, potentially giving attackers complete control over affected systems. The high CVSS score indicates that successful exploitation could result in a total compromise of the system's confidentiality, integrity, and availability (NVD).

The recommended mitigation is to avoid using versions 0.0.1~0.0.2 of the PyCrowdTangle package. Users should ensure they are using versions after 0.0.2 and verify their package sources. The malicious package was removed from the official PyPI repository, but users should be cautious when using mirror sites (GitHub Issue).
