CVE-2024-2260: 
Python vulnerability analysis and mitigation

A session fixation vulnerability (CVE-2024-2260) was discovered in the zenml-io/zenml application, affecting the authentication mechanism. The vulnerability was identified in April 2024 and relates to JWT tokens used for user authentication not being invalidated upon logout (NVD, Huntr).

The vulnerability is classified as CWE-384 (Session Fixation) and has been assigned a CVSS v3.0 base score of 4.2 (Medium) with the vector string CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N. The issue stems from the application's failure to properly invalidate JWT tokens after user logout, creating a security weakness in the session management system (NVD).

The vulnerability allows attackers to bypass authentication mechanisms by reusing a victim's JWT token that wasn't properly invalidated after logout. This could lead to unauthorized access to user accounts and potential exposure of sensitive information (NVD).

The vulnerability requires network access and user interaction to exploit, with high attack complexity as indicated by the CVSS metrics. The attack vector is network-based (AV:N) but requires high complexity (AC:H) to execute successfully (NVD).

A fix has been implemented and is available in the zenml-io/zenml repository through commit 68bcb3ba60cba9729c9713a49c39502d40fb945e. Users are advised to update to the latest version of the application to address this vulnerability (GitHub).
