CVE-2020-5224: Session key exposure through session list in Django User Sessions

• Severity: high (CVSS 8.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2020-01-24 · updated 2026-06-17
• Weakness: CWE-287

Description

In Django User Sessions (django-user-sessions) before 1.7.1, the views provided allow users to terminate specific sessions. The session key is used to identify sessions, and thus included in the rendered HTML. In itself this is not a problem. However if the website has an XSS vulnerability, the session key could be extracted by the attacker and a session takeover could happen.

Affected products

• Jazzband django-user-sessions: before 1.7.1 — fixed in 1.7.1

How to fix

Upgrade to a fixed version: Jazzband django-user-sessions 1.7.1. Check the vendor advisory for mitigations.
