CVE-2026-6213: CWE-807 Reliance on untrusted inputs in a security decision in Remote Spark (https://www.remotespark.com/) SparkView
CVE-2026-6213 is a critical vulnerability in Remote Spark's SparkView product before build 1122. It allows an unauthenticated attacker to bypass local connection checks and execute arbitrary code as root on the server. The vulnerability stems from reliance on untrusted inputs in security decisions. No official patch or remediation guidance is currently confirmed. The vulnerability has a maximum CVSS score of 10, indicating severe impact if exploited.
AI Analysis
Technical Summary
This vulnerability in Remote Spark SparkView (pre-build 1122) involves CWE-807 (reliance on untrusted inputs in a security decision) and CWE-290 (authentication bypass). It enables an attacker to bypass local connection verification mechanisms, potentially leading to arbitrary code execution with root privileges on the server hosting SparkView. The exploitability is high as it may be triggered by an unauthenticated attacker remotely. The CVSS 4.0 vector indicates network attack vector, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation results in complete compromise of the affected server, allowing an attacker to execute arbitrary code as root. This can lead to full system takeover, data compromise, and disruption of services. The vulnerability is critical due to the combination of unauthenticated remote access and root-level code execution.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the SparkView service to trusted networks and monitor for unusual activity. Avoid exposing the service directly to untrusted networks.
