StyleSmuggler Zero-Day Reportedly Enables Unauthenticated RCE on Magento and Adobe Commerce

Summary
Aikido reports an unauthenticated GraphQL-to-template RCE affecting current Magento Open Source and Adobe Commerce, with exploitation reported since September 4. The post conflicts on whether Adobe has issued hotfixes.
Key points
- The article describes StyleSmuggler as an unauthenticated RCE affecting current Magento Open Source and Adobe Commerce versions, including 2.4.9.
- The reported exploit injects PHP through GraphQL style properties; the payload is later executed during payment-failure email template rendering.
- Sansec reportedly observed attack traffic starting September 4, 2026, and reproduced the attack chain on clean installs of versions 2.4.7, 2.4.8, and 2.4.9.
- The article says confirmed intrusions installed a persistent Rust-based backdoor, and advises rotating Magento credentials if evidence of compromise is found.
- Aikido describes fixes for multiple package branches and suggests temporarily disabling GraphQL as an interim measure, while noting the impact on headless or PWA storefronts.
- Adobe's patch status is inconsistent in the article: its update says urgent hotfixes were released and lists CVE-2026-75650, while the body says Adobe had not issued a CVE or patch.
