Description

Django: cache middleware may expose private responses when unrelated request cookies are present

An issue was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16.

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.

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 Chris Whyland for reporting this issue.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality low, integrity none, availability none.

  • Integrity impact: None.
  • Availability impact: None.
