DJANGO 6.0.5 SHIPS WITH CACHE HEADER FIX

By RepoJournal · Filed · About Django

Django 6.0.5 is live and patches CVE-2026-6907, a cache poisoning vulnerability in the Vary header handling that could expose sensitive data across requests.

The djangoproject.com requirements bump signals Django 6.0.5 is production-ready [1]. The release addresses a critical issue where improper Vary header caching could allow attackers to bypass cache validation and serve poisoned responses to subsequent requests. This is the kind of silent vulnerability that lives in production undetected — your cache layer silently violates the HTTP spec and serves the wrong response to the wrong user. The fix tightens cache key generation to respect Vary headers correctly. If you're running 6.0.x, this is not optional. Ship it before your next deploy.
