Attack-Flow Graph

Executive Summary

CVE-2026-24186 is a high-severity vulnerability found in the NVIDIA FLARE SDK, specifically in its FOBS component. The vulnerability involves the unsafe deserialization of untrusted data, where an attacker can send a malicious FOBS-encoded message that triggers this unsafe deserialization process.

If successfully exploited, this vulnerability may allow the attacker to execute arbitrary code remotely on the affected system.

Compliance Impact

The provided information does not specify how this vulnerability affects compliance with common standards and regulations such as GDPR or HIPAA.

Impact Analysis

This vulnerability can have severe impacts including remote code execution, which means an attacker could potentially take control of the affected system.

Confidentiality impact: High - sensitive data could be exposed.
Integrity impact: High - data or system integrity could be compromised.
Availability impact: High - system availability could be disrupted.

Mitigation Strategies

To mitigate this vulnerability, it is important to prevent the processing of untrusted FOBS-encoded messages by the NVIDIA FLARE SDK.

Since the vulnerability involves unsafe deserialization triggered by malicious messages, immediate steps include restricting network access to the vulnerable component, applying any official patches or updates released by NVIDIA, and monitoring for suspicious activity related to FOBS message handling.
