Breaking: #93002 - Support for session transfer via FE_SESSION_KEY removed¶
See Issue #93002
TYPO3s Frontend Session Handling has had a custom feature by setting a custom
GET variable called
FE_SESSION_KEY to inject an existing session into a
Frontend Request without having a cookie sent as response.
This seldom used feature, which was limited to Frontend sessions only, and required knowledge of third-party integrations for TYPO3s encryption key to create such a session key is removed.
Features for integrating sessions should instead be built with custom AuthenticationServices, e.g. for Single-Sign-On functionality.
Calling TYPO3s Frontend with
FE_SESSION_KEY as GET parameter has no effect
anymore and will not pick up an existing session.
TYPO3 installations using this
FE_SESSION_KEY which is very rare and unlikely
to be used.
Build a custom Authentication Service to log in and use user session instead in a third-party extension.
