CVE-2026-97363: Monta monta.app WebSocket authentication rate limiting bypass

CVE-2026-97363 · Severity: high · CVSS 7.5 · Published 2026-10-02

Monta monta.app is a charging station management platform used to control EV charging infrastructure worldwide. An attacker can send unlimited authentication requests to the WebSocket API without restriction, enabling brute-force attacks to guess credentials or launch denial-of-service attacks that disrupt charging services. This could allow unauthorized access to sensitive charging data and station control functions.

Technologies: Monta.App. Vendors: Monta.

Quick answers

Is CVE-2026-97363 exploited in the wild?
No. Junglewise Threat Intelligence has no report of CVE-2026-97363 being exploited in the wild.
How severe is CVE-2026-97363?
High severity, with a CVSS score of 7.5, published 2 October 2026.
Which products and versions are affected?
Monta.App all versions.
Is there a fix for CVE-2026-97363?
No fixed version is recorded yet. Enable OCPP 1.6 Security Profile 2 (HTTP Basic Auth with TLS) to enforce authenticated connections, and rely on Monta's implemented rate limiting and automated connection throttling at the WebSocket layer to block abusive patterns including rapid reconnection and ID brute-forcing behavior. If you run it, Junglewise drafts a mitigation that fits your setup and applies it once you approve, with senior security engineers behind it.
How is CVE-2026-97363 attacked?
It is attacked over the network, in a hosted service.
Am I affected by CVE-2026-97363?
Check whether you run Monta.App at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

How to fix

Enable OCPP 1.6 Security Profile 2 (HTTP Basic Auth with TLS) to enforce authenticated connections, and rely on Monta's implemented rate limiting and automated connection throttling at the WebSocket layer to block abusive patterns including rapid reconnection and ID brute-forcing behavior.

Technical details

The WebSocket API in Monta monta.app lacks rate limiting on authentication requests (CWE-307), allowing attackers to conduct unrestricted brute-force attacks against authentication endpoints with no authentication required (network-accessible). Successful exploitation enables unauthorized access to charging station control and sensitive data, with potential for privilege escalation and system-wide compromise. Monta states they have implemented rate limiting at the WebSocket layer to block abusive connection patterns.
