EchelonGraph scoreLOW confidence

This medium-severity CVE scores 4.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Snipe-IT is an IT asset/license management system. Prior to 8.6.3, any activated account can request /maintenances/{id} and read maintenance records for assets in the same company without asset or maintenance permission. app/Http/Controllers/MaintenancesController.php show() renders the record without authorize(), while company-scoped route-model binding only prevents access to other companies. Disclosed fields include asset tags, suppliers, purchase costs, notes, and dates. This issue is fixed in version 8.6.3.
