CVE-2026-71362 is a critical incorrect authorization vulnerability in Adobe Commerce, Adobe Commerce B2B, and Magento Open Source. Improper handling of customer identity data in account sessions allows attacker-controlled customer-ID input from a failed account-edit flow to be retained and later copied into the attacker session. Session validation confirms only that the selected customer exists, rather than verifying that the session owner is authorized to act as that customer. An attacker can consequently replace the customer identity associated with their session with a victim customer identity. Affected releases include supported product branches through the July 2026 patch levels; Adobe addressed the issue in the August 2026 security updates and isolated patches.

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.
