Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Django versions 5.2 before 5.2.15 and 6.0 before 6.0.6 are affected. UpdateCacheMiddleware does not add Authorization to the Vary response header for requests that carry that header without Cache-Control: public, so a remote attacker making unauthenticated requests to the same URL can read private cached responses. Upgrade to Django 5.2.15 or 6.0.6. Earlier unsupported series were not evaluated and may also be affected.

Written 5 Nov 2026.
