CVE-2026-22093 in Service
Summary
by MITRE • 07/13/2026
The EVbee Service Android app uses TLS encrypted communication (HTTPS), but does not validate the certificate provided by the server. This allows an attacker on the network path between the app and EVbee server to intercept and manipulate the communication between the app and server. The traffic is weakly encrypted using RC4 with a hardcoded key, which allows an attacker to gain access to the communication. Part of this communication involves access codes to charging stations.
This issue affects EVbee Service: v1.4.101.00.

The vulnerability in EVbee Service Android application represents a critical security flaw that undermines the fundamental principles of secure communication and data protection. This issue stems from the application's failure to properly validate SSL/TLS certificates during HTTPS connections, creating a dangerous man-in-the-middle attack vector that compromises the entire communication channel between mobile users and the EVbee server infrastructure. The absence of certificate validation means that any attacker positioned within the network path can seamlessly intercept and manipulate data flowing between the client application and server endpoints without detection.
The technical implementation flaw manifests through multiple interconnected weaknesses that compound the security risk significantly. The application employs a deprecated encryption method using RC4 algorithm with a hardcoded key, which represents a severe violation of modern cryptographic standards and best practices. This approach directly contravenes industry guidelines such as those outlined in CWE-327, which specifically addresses the use of weak or broken cryptographic algorithms. The hardcoded nature of the encryption key eliminates any possibility of secure key rotation or management, making the entire communication channel vulnerable to passive interception and active manipulation by threat actors.
The operational impact of this vulnerability extends beyond simple data confidentiality breaches to encompass critical infrastructure security implications for electric vehicle charging networks. The intercepted communication contains sensitive access codes that provide unauthorized individuals with direct access to charging station facilities, potentially enabling theft of electrical power, disruption of charging services, or even physical tampering with charging infrastructure. This exposure represents a significant threat to both consumer privacy and the operational integrity of EVbee's charging network, as attackers could potentially gain unauthorized access to multiple charging stations through a single successful interception attack.
The vulnerability directly maps to several ATT&CK framework techniques including T1041 for data encryption for exfiltration and T1566 for credential harvesting through social engineering or compromised communication channels. The combination of certificate validation bypass with weak RC4 encryption creates an attack surface that aligns with the principles described in CWE-295, which addresses improper certificate validation issues. Organizations using this application face heightened risk of service disruption, financial loss due to unauthorized power consumption, and potential liability from compromised charging infrastructure access.
Effective mitigation strategies require immediate implementation of proper SSL/TLS certificate validation mechanisms along with complete removal of RC4 encryption implementations in favor of modern cryptographic standards such as AES-256 with secure key management protocols. The application must be updated to validate server certificates against trusted certificate authorities, implement proper certificate pinning where appropriate, and upgrade all encryption methods to comply with current industry standards including NIST SP 800-57 recommendations for cryptographic key management. Additionally, network-level security controls such as intrusion detection systems and traffic monitoring should be deployed to detect potential interception attempts and provide early warning capabilities for administrators to respond to suspicious activities within their charging network infrastructure.
