CVE-2026-71362 is a critical incorrect authorization vulnerability in Adobe Commerce, Adobe Commerce B2B, and Magento Open Source. The flaw stems from improper handling of customer identity within account sessions, allowing a remote attacker to switch a customer session to another customer account. As a result, an unauthenticated attacker can access resources associated with a different customer context and effectively escalate privileges without requiring administrator access or user interaction. Public reporting indicates the issue was observed being targeted shortly after disclosure. Affected releases include supported product versions up to the July 2026 patch level, and Adobe corrected the issue in the August 2026 security updates and isolated patch set APSB26-92.

This repository is a self-contained Docker lab and working Python PoC for CVE-2026-71362, an incorrect authorization flaw in Adobe Commerce / Magento Open Source that allows customer-session identity switching and account takeover. The main exploit logic is in exploit/poc.py, which automates account registration, session poisoning via POST /customer/account/editPost with a malicious id field, and trigger/verification via GET /customer/account/edit and /customer/section/load. The exploit does not deliver code execution; instead, it abuses vulnerable session/customer object handling to overwrite the authenticated session's customer_id and impersonate arbitrary customers. Repository structure: exploit/poc.py contains the operational PoC; docker-compose.yml plus php/Dockerfile and php/entrypoint.sh build a disposable Magento environment with MariaDB, Redis, OpenSearch, PHP-FPM, and nginx; patch/Edit.vulnerable.php, patch/Edit.patched.php, and patch/official-APSB26-92-module-customer.patch document and toggle the vulnerable/fixed controller implementation; scripts/patch.sh and scripts/unpatch.sh provide A/B testing of the fix; docs/ROOTCAUSE.md explains the vulnerable code path and docs/DETECTION.md provides detection/WAF guidance. Exploit capability: the PoC registers an attacker account, optionally creates a victim account for demonstration, then iterates customer IDs or targets a specific victim ID. For each target, it submits a deliberately failing editPost request carrying id=<victim_id>, causing attacker-controlled customer_form_data to persist in session. A subsequent GET to /customer/account/edit causes Magento's vulnerable populateWithArray() flow to copy id onto the customer object and Session::setCustomerData() to overwrite session customer_id. The script then reads victim identity/PII from account pages and AJAX customer section data. This is a real exploit, not merely detection, and is operational but basic/hardcoded rather than framework-weaponized.
