CVE-2022-31605

CWE-502Published: July 1, 2022· Updated: Jun 17, 2026

9.8

CVSS v3.1

Official Description

NVFLARE, versions prior to 2.1.2, contains a vulnerability in its utils module, where YAML files are loaded via yaml.load() instead of yaml.safe_load(). The deserialization of Untrusted Data, may allow an unprivileged network attacker to cause Remote Code Execution, Denial Of Service, and Impact to both Confidentiality and Integrity.

Risk Analysis

NVFLARE versions prior to 2.1.2 use an unsafe YAML loading method, which can lead to arbitrary code execution. Given the 9.8 CVSS score, this represents a severe risk to the confidentiality and integrity of the system.

No public exploit is known for this issue, and it is not in CISA KEV. It is remotely exploitable by an unprivileged attacker.

Recommended Action

Upgrade NVFLARE to version 2.1.2 or later to ensure the use of safe YAML loading practices.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2022-31605 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

From a weakness classification perspective (CWE-502): Insecure deserialization vulnerabilities allow attackers to inject malicious objects during deserialization, potentially enabling remote code execution.
