Mercator CVE Configuration Vulnerable to Server-Side Request Forgery (SSRF)

Mercator is an open source web application that enables mapping of the information system. Prior to version 2025.05.19, a Server-Side Request Forgery (SSRF) vulnerability exists in Mercator's CVE configuration panel (`/admin/config/parameters`). The `testProvider()` method in `ConfigurationController` passes user-supplied input directly to `curl_init()` without validating the scheme, hostname, or destination IP address. An authenticated user with the `configure` permission can force the Mercator server to issue arbitrary outbound network requests. The suffix `/api/dbInfo` appended to the URL can be bypassed by injecting a `#` fragment character (e.g. `http://TARGET/PATH#`), allowing full control over the target URL. No scheme whitelist, host whitelist, or private/loopback IP block is applied. The `telnet://` scheme can be used for internal port scanning; the `gopher://` scheme enables interaction with unauthenticated internal services (Redis, Memcached), potentially leading to Remote Code Execution under specific deployment conditions. Version 2025.05.19 patches the issue.

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.
