CVE-2026-35192: Session fixation via public cached pages and SESSION_SAVE_EVERY_REQUEST
Noroxi assessment
Priority: Monitor (action score 9/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.54% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. No account or password is required. No special conditions are required; it is repeatable.
- Fixed version: djangoproject Django 5.2.14, 6.0.5.
Low priority for now. Upgrade to djangoproject Django 5.2.14, 6.0.5 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
An issue was discovered in 6.0 before 6.0.5 and 5.2 before 5.2.14. Response headers do not vary on cookies if a session is not modified, but `SESSION_SAVE_EVERY_REQUEST` is `True`. A remote attacker can steal a user's session after that user visits a cached public page. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Cantina for reporting this issue.
