Description

An issue was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16.<br /> `UpdateCacheMiddleware` and the `cache_page()` decorator cache responses that vary on cookies when the incoming request carries unrelated cookies, which allows remote attackers to read private data from the shared cache.<br /> Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.<br /> Django would like to thank Chris Whyland for reporting this issue.
