Overview
The CVE-2025-9815 is a significant vulnerability discovered in the alaneuler batteryKid application, up to version 2.1, specifically on macOS systems. This vulnerability, located in an unknown function of the file PrivilegeHelper/PrivilegeHelper.swift, allows an attacker to bypass authentication mechanisms, potentially resulting in unauthorized system access or data leakage.
Vulnerability Summary
CVE ID: CVE-2025-9815
Severity: High (CVSS: 7.8)
Attack Vector: Local
Privileges Required: None
User Interaction: None
Impact: Potential system compromise and data leakage
Affected Products
A new way to communicate
Ameeba Chat is built on encrypted identity, not personal profiles.
Message, call, share files, and coordinate with identities kept separate.
- • Encrypted identity
- • Ameeba Chat authenticates access
- • Aliases and categories
- • End-to-end encrypted chat, calls, and files
- • Secure notes for sensitive information
Private communication, rethought.

alaneuler batteryKid | Up to version 2.1
How the Exploit Works
The exploit works by manipulating an unknown function within the PrivilegeHelper/PrivilegeHelper.swift file of the alaneuler batteryKid application. This function, which is related to the NSXPCListener component, lacks proper authentication, allowing attackers to execute commands or access data without valid credentials. The exploitation is possible on the local host, meaning the attacker needs to have access to the host system.
Conceptual Example Code
Given the nature of this vulnerability, a conceptual exploitation might involve a rogue script or application executing on the local host. Here’s a simplified example in pseudocode:
import Foundation
let connection = NSXPCConnection(serviceName: "com.alaneuler.batteryKid.PrivilegeHelper")
connection.remoteObjectInterface = NSXPCInterface(with: PrivilegeHelperProtocol.self)
connection.resume()
if let service = connection.remoteObjectProxyWithErrorHandler({ error in print("Received error:", error) }) as? PrivilegeHelperProtocol {
service.executeCommand("malicious_command")
}In this example, a malicious command is sent to the PrivilegeHelper service without any form of authentication, exploiting the vulnerability.
Mitigation
Users of alaneuler batteryKid are strongly advised to apply the latest patch released by the vendor, which addresses this vulnerability. In cases where immediate patching isn’t feasible, the use of intrusion detection systems (IDS) or web application firewalls (WAF) can serve as temporary mitigation measures. Regular monitoring and system audits can also help in detecting any anomalies related to this vulnerability.
