Description
Improper neutralization of special elements in data query logic in the polymorphic relation handling of the MongoDB integration for Laravel can cause a caller-supplied relation identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence a stored relation identifier may cause an affected application to return a document other than the intended relation target.
