A Deep Dive into a Potential Privilege Escalation Issue
1 min read
Summary
A security researcher identified a privilege escalation vulnerability involving Shopify’s Multipass feature, which could allow an attacker to gain unauthorized access to sensitive information or systems.
Privilege escalation allows users to obtain greater permissions than they originally had, which can be harmful if used unlawfully.
This article breaks down the technical details of the Multipass vulnerability, its implications, and identification strategies for similar issues in web applications.
It is intended to be an easily understandable report of the security incident, with practical steps on identifying such vulnerabilities.
Two types of privilege escalation exist: vertical (e.g., a user gains admin privileges) and horizontal (e.g., an attacker accesses multiple users’ data).
