Django Uses Persistent Cookies Containing Sensitive Information
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
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 thanks Cantina for reporting this issue.
