CVE-2026-71362Known exploitationNetwork attack vector

Unauthenticated account takeover via session identity switch

Published Aug 11, 2026 · Updated Aug 11, 2026

Incorrect authorization in Adobe Commerce, Adobe Commerce B2B, and Magento Open Source allows remote attackers to take over customer accounts. Customer identity handling in the account session permits an attacker-controlled session to switch to another customer's identity. No existing account, administrator access, or user interaction is required; takeover exposes the victim's account and private customer data.
