CVE-2026-24186: CWE-502 Deserialization of Untrusted Data in NVIDIA FLARE SDK
NVIDIA FLARE SDK contains a vulnerability in FOBS, where an attacker may cause deserialization of untrusted data by sending a malicious FOBS- encoded message. A successful exploit of this vulnerability might lead to code execution.
AI Analysis
Technical Summary
CVE-2026-24186 is a deserialization of untrusted data vulnerability in NVIDIA FLARE SDK's FOBS component. This flaw allows an attacker to craft a malicious FOBS-encoded message that, when processed by vulnerable versions of the SDK (all versions prior to 2.7.2), may result in arbitrary code execution. The vulnerability is rated high severity with a CVSS 3.1 score of 8.8, reflecting network attack vector, low attack complexity, required privileges, no user interaction, and high impact on confidentiality, integrity, and availability. No official patch or remediation level has been published by NVIDIA as of the data provided.
Potential Impact
Successful exploitation could allow an attacker with network access and limited privileges to execute arbitrary code on the system running the vulnerable NVIDIA FLARE SDK. This could compromise confidentiality, integrity, and availability of the affected system. There are no reports of active exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the NVIDIA vendor advisory for current remediation guidance. Until an official fix is released, avoid processing untrusted FOBS-encoded messages or restrict network access to the vulnerable component to trusted sources only.
