description

Apostrophe versions through 4.34.0 can allow lower-privileged users to access and modify documents in content types whose viewRole should exclude them. This requires a type where the caller meets its editRole but not its viewRole, such as a contributor-accessible edit role paired with an administrator-only view role.

mitigation

Upgrade apostrophe to version 4.34.1 or later. Until upgraded, configure affected types so their editRole is at least as restrictive as their viewRole and review contributor access.

fixed in 4.34.1
