CVE-2026-75650: Adobe Commerce and Magento Improper Neutralization of Special Elements Used in a Template Engine Vulnerability

Should you act?

Exploited: patch now if you run it

CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• Yes, if you run Adobe Commerce and Magento. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2026-09-08, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-09-11; treat that as the outer limit, not the target.
• EPSS 3.9%, percentile 90: FIRST’s model estimates a 3.9% chance of exploitation activity in the next 30 days, higher than 90% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
• Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
• Editorial verdict: Act now. Magento StyleSmuggler CVE-2026-75650: Exploited Pre-Auth RCE — Any self-run Magento or Adobe Commerce store without the September hotfix should be presumed compromised: patch, then scan, then rotate the encryption key and every credential it protects, and add the October fix for the follow-on BlockStrap bug.
