Customer session disruption via cached 404 cookies
Published Mar 6, 2024 · Updated Aug 5, 2024
Improper caching in Shopware 6.5.8.0 through 6.5.8.6 allows remote attackers to clear customer carts or sessions via 404 requests. NotFoundSubscriber caches a 404 response after Symfony adds a new session cookie, causing later cookie-less requests to receive that cached session identifier. Exposure requires the Symfony session handler; the PHP Redis session handler bypasses this code path, and reported impact is limited to logout or cart clearing.
