CVE-2026-49344
Mercator has a Personal Identifiable Information Leak from Query Executor feature
Mercator is an open source web application that enables mapping of the information system. Prior to version 2025.05.19, Mercator's Query Engine (/admin/queries/execute) accepts a JSON DSL (from / select / filters / traverse / output), translates it into an Eloquent query, and returns results as JSON. The controller method QueryController::execute() does not enforce an authorization gate, unlike store() and massDestroy() in the same controller which are correctly protected. As a result, any authenticated account — including the read-only Auditor role — can query models beyond its intended scope, including the User model. Additionally, the password column, although declared $hidden, is not excluded from filter predicates, which allows it to be used in LIKE conditions. The schema() and schemaModel() endpoints of the same controller are similarly unguarded. The Query Engine is read-only; integrity and availability are not affected. Version 2025.05.19 patches the issue.
