This update provides immediate defense against a high-severity, actively exploited zero-day vulnerability targeting Adobe Commerce and Magento Open Source storefronts.
Key Findings
- Adobe Commerce and Magento RCE (CVE-2026-75650 / “StyleSmuggler”): Unauthenticated Remote Code Execution (RCE) vulnerability caused by improper neutralization of special elements in the platform’s template engine. Unauthenticated attackers can inject arbitrary PHP payloads through style properties to execute system commands and deploy persistent malware.
Impact
This emergency rule provides immediate edge-level mitigation and virtual patching, origin applications must be urgently updated. We strongly recommend to apply the hotfix outlined in Adobe Security Bulletin APSB26-146 and immediately rotate all potentially exposed encryption keys, integration tokens, and system credentials, as patching alone does not remediate an existing compromise.
