CVE-2025-14979 is a vulnerability identified in AirVPN's Eddie VPN client version 2.24.6 for macOS. The root cause is an insecure XPC (Interprocess Communication) service that has incorrect permission assignments, classified under CWE-732 (Incorrect Permission Assignment for Critical Resource). This misconfiguration allows local, unprivileged users to escalate their privileges to root, bypassing normal security controls. The vulnerability does not require user interaction or authentication, making it easier for an attacker with local access to exploit. The CVSS 4.0 vector indicates a local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and high impact on confidentiality, integrity, and availability (VC:H/VI:H/VA:H). This means an attacker who already has limited access to the system can fully compromise it by gaining root privileges. The vulnerability affects only version 2.24.6 of Eddie on macOS, and no patches or fixes have been linked yet. There are no known exploits in the wild at the time of publication, but the high severity score suggests that exploitation could have serious consequences. The vulnerability is significant because VPN clients often run with elevated privileges and have access to network configurations, making root access particularly dangerous.

The primary impact of CVE-2025-14979 is local privilege escalation to root on macOS systems running AirVPN Eddie 2.24.6. This allows an attacker with local access—such as a malicious insider, compromised user account, or malware that has gained limited execution rights—to gain full control over the system. With root privileges, the attacker can modify system files, install persistent malware, disable security controls, intercept or manipulate network traffic, and access sensitive data. This undermines the confidentiality, integrity, and availability of the affected system. Organizations relying on AirVPN Eddie on macOS for secure communications could face severe security breaches, data exfiltration, or system sabotage. The vulnerability's local attack vector limits remote exploitation but does not diminish the risk in environments where local access is possible, such as shared workstations, compromised endpoints, or multi-user systems. The absence of known exploits currently reduces immediate risk but does not preclude future weaponization. The impact is particularly critical in sectors with high security requirements, including government, finance, and critical infrastructure.

To mitigate CVE-2025-14979, organizations should immediately identify and isolate macOS systems running AirVPN Eddie version 2.24.6. Since no official patch is currently linked, users should consider the following specific actions: 1) Temporarily discontinue use of the affected Eddie version and revert to a previous secure version if available or use alternative VPN clients with verified security. 2) Restrict local user access to macOS systems running Eddie to trusted personnel only, minimizing the risk of local exploitation. 3) Employ macOS security features such as System Integrity Protection (SIP) and Endpoint Detection and Response (EDR) tools to monitor for suspicious privilege escalation attempts. 4) Audit and harden permissions on XPC services and related resources manually if feasible, ensuring they are not accessible by unprivileged users. 5) Monitor system logs for unusual activity indicative of privilege escalation attempts. 6) Stay alert for official patches or updates from AirVPN and apply them promptly once available. 7) Educate users about the risks of local access and enforce strong endpoint security policies to prevent unauthorized physical or remote local access. These targeted mitigations go beyond generic advice by focusing on access control, monitoring, and interim usage policies until a patch is released.
