1. What is SessionReaper?

SessionReaper is a newly discovered security vulnerability that affects Adobe Commerce and Magento Open Source stores.
It allows attackers to hijack active user sessions, meaning they can impersonate logged-in users — including administrators — without needing to log in themselves.

This could lead to:

  • Unauthorized access to admin or customer accounts
  • Data breaches and theft of customer information
  • Compromised checkout and order data
  • Potential damage to website reputation and security

Adobe has released a security patch that resolves this issue by strengthening session management and preventing attackers from reusing or stealing session tokens.
