A serious vulnerability called SessionReaper (CVE-2025-54236) in Adobe Commerce and Magento Open Source could allow attackers to take control of customer accounts through the REST API. Improper input validation and insecure session storage are at the heart of the issue.
This flaw is especially risky for online retailers, digital platforms with user logins, and businesses using third-party plugins. If left unpatched, it could lead to account takeovers, financial fraud, and widespread breach of customer trust.
What You Should Do
- Patch affected versions immediately
- Replace insecure session storage (file-based) with safer alternatives like database or Redis storage
- Audit custom extensions for security vulnerabilities
- Monitor login activity and look out for unusual patterns of account behavior
- Strengthen REST API security and enforce strict input validation
