Our Threat Modeling Tool Helps you to Perform Structured Threat Modeling at Scale

It’s easy to get started with threat modeling and gain initial security value from it. However, rolling out structured threat modeling at scale is a different matter. Our threat modeling tool helps you to get the most of threat modeling, in order to apply security by design and default.

  • Powerful assessment engine to understand potential threats and security weakness.
  • Flexible Diagram engine to visualize components and communication flows in play.
  • Clear reporting and metrics for compliance demonstration.

CVE-2026-12191: Comma AI Openpilot Unsafe Pickle Deserialization Vulnerability (CVSS 7.8)

Overview CVE-2026-12191 is a high-severity insecure deserialization vulnerability in Comma AI Openpilot, an open-source autonomous driving research platform. The vulnerability exists in the modeld.py module, which uses Python’s pickle.load() and pickle.loads() to deserialize untrusted data without any validation or sanitization. A local attacker with access to the system can craft a malicious pickle payload to achieve arbitrary code execution in the context of the…

CVE-2026-54411: Linux-PAM pam_userdb Module Timing Side-Channel Vulnerability (CVSS 5.9)

What Is CVE-2026-54411? CVE-2026-54411 is a timing side-channel vulnerability in the pam_userdb module of Linux-PAM. The issue resides in pam_userdb.c, where the plaintext password comparison routine exhibits a measurable timing discrepancy. A local attacker can exploit this by measuring response times to systematically enumerate valid usernames from the user database backend. The vulnerability carries a CVSS score of 5.9 (Medium), reflecting the local attack…
