# Which Problems Are Solved Zitadel v4.7.2 fixed a security issue by switching to the permission v2 framework for user APIs. It appears that systems that are running since before v2.68 that were affected by a precision bug in the eventstore, which was fixed in that version. The precision bug results in certain events being "skipped" while being projected into the fields table, used by the new permission system. This caused certain membership roles to be missing, resulting in empty user lists when executed by the affected member. The permission system basically finds no matching memberships and therefore returns no users at all. # How the Problems Are Solved After research we concluded that the legacy membership projections are projected correctly. This PR synchronizes the projected state into the fields table. As the membership roles are not marked unique, all rows are first deleted and then the correct membership roles are then inserted. The operation happens in a single transaction, during which the fields table will remain locked for modifications. This to prevent possible concurrent modifications to membership states. # Additional Changes - none # Additional Context - Introduced in https://github.com/zitadel/zitadel/commit/0e17d0005a98ccbf92139961ef702ef03208ffd3 - Released in [v4.7.2](https://github.com/zitadel/zitadel/releases/tag/v4.7.2) - Related: https://github.com/zitadel/zitadel/issues/8863 --------- Co-authored-by: Silvan <[email protected]>
