StyleSmuggler: Magento and Adobe Commerce 0-day RCE (CVE-2026-75650) under active attack
Sansec details actively exploited StyleSmuggler 0-day (CVE-2026-75650, CVSS 10.0) unauthenticated RCE in Magento and Adobe Commerce, patched by Adobe hotfix APSB26-146.
Sansec is investigating StyleSmuggler, an actively exploited unauthenticated remote code execution chain in Magento Open Source and Adobe Commerce, now tracked as CVE-2026-75650 with CVSS 10.0. Adobe released hotfix VULN-39341 via APSB26-146 (priority 1) on September 7 for versions 2.4.4 through 2.4.9, but stores were being exploited for roughly three days before the fix existed. The implant is a Rust backdoor that disguises itself as kworker, fc-cache, or chronyd processes and exfiltrates host data in MessagePack records sent as fake NTP replies over UDP port 123. Adobe advises rotating the encryption key and every credential it protected, and Sansec stresses patching does not clean already-compromised stores.
Unpatched Magento and Adobe Commerce Zero-Day Exploited to Backdoor Online Stores
Sansec reports active exploitation of an unpatched zero-day, dubbed StyleSmuggler, in Magento and Adobe Commerce, letting attackers backdoor online store servers without authentication.
Sansec disclosed on September 5 that attackers are exploiting an unpatched vulnerability, named StyleSmuggler, in Magento Open Source and Adobe Commerce to achieve unauthenticated remote code execution, with attacks observed starting September 4. All current versions including 2.4.9 are affected, and Adobe has published no advisory, CVE, patch, or workaround, with the next scheduled security release on September 8. Hosting firm Disrex Group independently confirmed two compromised stores (running 2.4.8 and 2.4.7-p2), both breached within the roughly eight-hour window before Sansec's blocking rules went live. The implant is a ~1.9 MB statically linked Rust binary disguised as a Linux kworker process, re-adding a cron entry every five minutes and in one case reading Magento sessions directly from Redis with no outbound traffic.
Adobe Commerce CVE-2026-71362 Comes Under Attack Shortly After Public Disclosure
Attackers began exploiting critical Adobe Commerce flaw CVE-2026-71362 (CVSS 9.1) for unauthenticated customer account takeover shortly after patch release.
Sansec blocked the first exploitation attempts of CVE-2026-71362 immediately after Adobe published its advisory. The flaw lets unauthenticated attackers switch a customer session to another customer account, hijacking accounts and accessing private data without credentials, admin privileges or user interaction. It affects Adobe Commerce, Commerce B2B and Magento Open Source versions through the July 2026 patches, and Adobe issued isolated patch files APSB26-92 fixing seven vulnerabilities, including stored cross-site scripting and authorization issues.
