Technical summary
nbviewer through 1.0.1 contains a path traversal vulnerability in LocalFileHandler.can_show() that uses string-prefix comparison instead of proper path validation. Attackers can read files from sibling directories outside the configured root by requesting paths that share the root as a textual prefix, disclosing unintended notebooks and credentials.

About the Vulnerability Pulse CVE Feed
The Vulnerability Pulse feed tracks live CVE advisories sourced from the National Vulnerability Database and vendor security disclosures. It is designed for SOC analysts, IT administrators, and security teams who need a fast, filterable view of current vulnerabilities without digging through raw NVD data.
How to Use the CVE Advisory Tracker
Use the severity filters to narrow results to Critical or High priority vulnerabilities. Filter by vendor to focus on software and hardware relevant to your environment. Export to CSV for reporting, ticketing, or patch prioritization workflows.
What Is a CVE Advisory?
A CVE (Common Vulnerabilities and Exposures) advisory is a public disclosure of a security vulnerability assigned a unique identifier by MITRE. Advisories include severity scores (CVSS), affected versions, and remediation guidance. Monitoring CVE advisories is a core function of vulnerability management programs and SOC operations.
CVE Analysis & Writeups
For in-depth analysis of specific vulnerabilities, visit the IT Knowledge Bases blog for CVE breakdowns, exploitation analysis, and remediation guidance written for security practitioners.
