Alert meAnalysisAIv1 – Mar 12, 2026
WebSocket session management in charging station backends allows multiple connections using identical session identifiers, enabling attackers to hijack legitimate sessions and intercept commands or impersonate authorized stations. Unauthenticated remote attackers can exploit this predictable identifier scheme to displace active connections, redirect backend communications, or launch denial-of-service attacks against the charging infrastructure. The vulnerability affects any deployment relying on this WebSocket backend without an available patch.
Earlier versions of this analysis (1)
The WebSocket backend uses charging station identifiers to uniquely associate sessions but allows multiple endpoints to connect using the same session identifier. [CVSS 7.3 HIGH]

Technical ContextAI · show details
Classified as CWE-613 (Insufficient Session Expiration). The WebSocket backend uses charging station identifiers to uniquely associate sessions but allows multiple endpoints to connect using the same session identifier. This implementation results in predictable session identifiers and enables session hijacking or shadowing, where the most recent connection displaces the legitimate charging station and receives backend commands intended for that station. This vulnerability may allow unauthorized users to authenticate as other users or enable a malicio

Lifecycle Timeline
3DescriptionCVE.org
The WebSocket backend uses charging station identifiers to uniquely associate sessions but allows multiple endpoints to connect using the same session identifier. This implementation results in predictable session identifiers and enables session hijacking or shadowing, where the most recent connection displaces the legitimate charging station and receives backend commands intended for that station. This vulnerability may allow unauthorized users to authenticate as other users or enable a malicious actor to cause a denial-of-service condition by overwhelming the backend with valid session requests.
Executive ViewAI
A high-severity vulnerability in our WebSocket backend allows attackers to hijack charging station sessions by connecting multiple endpoints with identical session identifiers, potentially enabling unauthorized access to critical infrastructure and customer data. This affects all systems relying on the vulnerable WebSocket backend and requires immediate mitigation until a patch becomes available.
Implement WAF rules to reject multiple concurrent connections using identical session identifiers; enforce IP-based session binding to prevent session reuse across different endpoints; enable real-time monitoring and alerting for anomalous WebSocket connection patterns; restrict WebSocket endpoint access to known, whitelisted IP ranges; implement network segmentation to isolate charging station infrastructure from general corporate network; require mutual TLS (mTLS) authentication for WebSocket connections; disable WebSocket feature if operationally acceptable; increase session token complexity and rotation frequency.
