CVE-2025-10906 is a high-severity vulnerability affecting Magnetism Studios Endurance versions up to 3.3.0 on macOS. The flaw exists in the NSXPC Interface component, specifically within the function loadModuleNamed:WithReply located in the helper binary at /Applications/Endurance.app/Contents/Library/LaunchServices/com.MagnetismStudios.endurance.helper. This vulnerability results from missing authentication checks during interprocess communication (IPC) via the NSXPC mechanism, allowing an attacker with local access to manipulate the function call without proper verification. Consequently, an attacker can potentially execute unauthorized actions or load arbitrary modules, compromising the integrity and confidentiality of the application and possibly the host system. The attack vector requires local access, meaning the attacker must have some level of access to the target machine, but no privileges or user interaction are necessary. The published exploit indicates that the vulnerability is exploitable in practice, increasing the urgency for mitigation. The CVSS 4.0 score of 8.6 reflects a high impact on confidentiality, integrity, and availability, with low attack complexity and no required privileges or user interaction, making it a significant threat to affected users.

For European organizations, the impact of this vulnerability can be substantial, particularly for those using Magnetism Studios Endurance on macOS devices. Endurance is a productivity and focus enhancement tool, often used by knowledge workers and creative professionals. Exploitation could lead to unauthorized code execution or privilege escalation on affected endpoints, potentially allowing attackers to bypass security controls, access sensitive information, or disrupt user workflows. This could result in data breaches, intellectual property theft, or operational downtime. Given the local attack requirement, insider threats or compromised user accounts pose a higher risk. Organizations with remote or hybrid workforces using macOS devices are particularly vulnerable if endpoint security is lax. The absence of authentication in the IPC mechanism undermines trust boundaries within the application, which could be leveraged to pivot to further attacks on the network or escalate privileges. Although no widespread exploitation is currently reported, the availability of a public exploit increases the likelihood of targeted attacks, especially in sectors with high-value data or intellectual property.

To mitigate this vulnerability, European organizations should prioritize updating Magnetism Studios Endurance to a patched version once available from the vendor. Until a patch is released, organizations should implement strict endpoint security controls, including limiting local access to trusted users only and enforcing strong user authentication and authorization policies. Employ application whitelisting and monitor IPC traffic on macOS endpoints to detect anomalous behavior related to the Endurance helper process. Use macOS security features such as System Integrity Protection (SIP) and Endpoint Detection and Response (EDR) solutions to detect and block unauthorized module loading or suspicious process interactions. Additionally, conduct user awareness training to reduce the risk of insider threats and ensure that local accounts have minimal privileges. Regularly audit installed software versions and remove or restrict use of vulnerable versions of Endurance in sensitive environments. Network segmentation can also help contain potential lateral movement if exploitation occurs.
