CVE-2026-24186: CWE-502 Deserialization of Untrusted Data in NVIDIA FLARE SDK
NVIDIA FLARE SDK versions prior to 2.7.2 contain a deserialization vulnerability in the FOBS component. An attacker can send a malicious FOBS-encoded message that triggers deserialization of untrusted data, potentially leading to remote code execution. This vulnerability has a high severity score of 8.8. No official patch or remediation guidance has been provided yet by NVIDIA. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
CVE-2026-24186 is a CWE-502 deserialization of untrusted data vulnerability in NVIDIA FLARE SDK's FOBS component. It allows an attacker to send crafted FOBS-encoded messages that cause the SDK to deserialize malicious data. Successful exploitation may result in arbitrary code execution. The vulnerability affects all versions prior to 2.7.2. The CVSS v3.1 base score is 8.8, indicating high severity with network attack vector, low attack complexity, requiring low privileges and no user interaction, and impacts confidentiality, integrity, and availability.
Potential Impact
Exploitation of this vulnerability could allow an attacker to execute arbitrary code remotely within the context of the vulnerable FLARE SDK process. This could lead to full compromise of the affected system or application using the SDK. The high CVSS score reflects the critical impact on confidentiality, integrity, and availability.
Mitigation Recommendations
No official patch or remediation level has been announced by NVIDIA as of the published date. Users should monitor NVIDIA's advisories for updates and apply any forthcoming patches promptly. Until a fix is available, consider restricting network access to the FLARE SDK service or implementing input validation controls to mitigate untrusted data deserialization risks.
