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.

AnalysisAI
NoSQL injection in the MongoDB integration for Laravel (laravel-mongodb PHP) allows an authenticated low-privilege user to manipulate polymorphic relation identifiers, causing the application to return documents outside the intended relation target. The vulnerability (CWE-943) exploits the boundary between data and query logic in MongoDB's operator-based query model: a crafted relation identifier stored by an attacker is later interpreted as a MongoDB query condition rather than a literal string during relation resolution. …
