CVE-2026-35192

MEDIUM

6.5

CVSS v3

Description

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.
