- Summary
- Prevent cache poisoning via a Response Content-Type header in Symfony
- Details
-
Description
When a
Responsedoes not contain aContent-Typeheader, Symfony falls back to the format defined in theAcceptheader of the request, leading to a possible mismatch between the response's content andContent-Typeheader. When the response is cached, this can lead to a corrupted cache where the cached format is not the right one.Resolution
Symfony does not use the
Acceptheader anymore to guess theContent-Type.The patch for this issue is available here for the 4.4 branch.
Credits
I would like to thank Xavier Lacot from JoliCode for reporting & Yonel Ceruto and Tobias Schultze for fixing the issue.
