High severity vulnerability in StudioCMS. The S3 storage manager's `isAuthorized()` function is declared `async` (returns `Promise<boolean>`) but is called without `await` in both the POST and PUT handlers.

Unauthenticated remote attackers can impersonate electric vehicle charging stations in Everon's api.everon.io platform via unprotected OCPP WebSocket endpoints. By connecting with a known or discovered station identifier, attackers gain full control to issue OCPP commands as legitimate chargers, manipulate charging session data, escalate privileges within the charging network infrastructure, and corrupt backend telemetry. CISA ICS-CERT reports this vulnerability affecting critical EV charging infrastructure. Despite 9.3 CVSS score indicating critical severity, EPSS score of 0.09% (25th percentile) suggests exploitation requires specialized knowledge of OCPP protocol and charging network architecture rather than mass automated scanning.

Remote denial-of-service and credential brute-force attacks against Everon's api.everon.io WebSocket interface allow unauthenticated attackers to disrupt electric vehicle charging infrastructure by overwhelming the authentication endpoint with unlimited login attempts, suppressing or mis-routing charger telemetry data, or compromising accounts through password guessing. EPSS score is low (0.06%, 20th percentile) indicating limited observed exploitation activity, though the network-accessible, zero-authentication attack vector poses clear operational risk to charging station operators relying on this API for fleet management.

Unrestricted authentication requests in the WebSocket API enable attackers to launch denial-of-service attacks against charger telemetry systems or execute brute-force attacks to gain unauthorized access. The vulnerability affects systems relying on this API without rate-limiting controls, and no patch is currently available. An unauthenticated remote attacker can exploit this over the network with minimal complexity to disrupt service availability or compromise system access.

Navtor NavBox devices allow unauthenticated remote attackers to retrieve sensitive operational data including ECDIS information, device identifiers, and service logs by sending HTTP requests to the unprotected API on port 8080.
