Leaks of sensitive user data

Package

npm time-machine-site (npm)

Affected versions

<= v1.0

Patched versions

v1.1 — All third-party links have been replaced with self-hosted or CDN-secured alternatives.

Description

The Time-Machine personal website previously relied on external, unaudited third-party hosts to serve images and videos. These external URLs were embedded in multiple pages and components, exposing users to potential risks such as IP leakage, content swapping, or malicious media injection.

Because these media hosts are not under project control, users’ interactions (e.g., page views) could be tracked or exploited without consent, violating privacy and security best practices.

Impact:
• Passive user tracking via remote media requests
• Content injection via swapped/expired image links
• Poor content integrity assurance
• Potential GDPR/privacy violations

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
