jupyterlab — Vulnerabilities & Security Advisories 7

JupyterLab serves as an interactive development environment for data science and computational research, enabling code execution, visualization, and collaboration. Historically, it has been susceptible to remote code execution (RCE) through crafted notebook files, cross-site scripting (XSS) via malicious inputs, and privilege escalation in multi-user deployments. Security incidents often stem from improper input validation and insufficient sandboxing of executed code. With seven CVEs documented, common vulnerabilities include path traversal attacks and authentication bypasses. While JupyterLab remains widely adopted, users must implement strict access controls and input sanitization to mitigate risks, particularly in shared or internet-facing deployments where untrusted notebooks pose significant threats.
