- Exploitation
- CISA lists CVE-2026-75650 as exploited in the wild.
NCSC-NL issued a high-priority advisory (NCSC-2026-0344) for CVE-2026-75650, a critical improper neutralization vulnerability in the template engine of Adobe Commerce and Magento. The flaw allows an attacker to execute arbitrary code remotely without any user interaction, by abusing a modified scope to escalate privileges or alter the execution context. The vulnerability carries a maximum CVSS v3 score of 10.0.
Adobe has confirmed this vulnerability is already being actively exploited in the wild, making immediate patching a priority for all organizations running affected Adobe Commerce or Magento installations. Adobe has released updates to address the issue; defenders should apply these patches immediately and review Adobe's official references for affected version details and further remediation guidance. Given the unauthenticated, zero-click RCE nature of this flaw combined with confirmed active exploitation, this represents a severe risk to any internet-facing e-commerce platform running the affected software.

Detection guidance
Suspicious Web Process Spawning from PHP/Apache
A behavioural hunt for the technique in general, not a signature for the CVEs this report names.
Detects PHP or Apache web server processes spawning cmd.exe, powershell.exe, or bash with unusual parent/child relations indicating post-exploitation code execution. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries its detections (Splunk SPL already written, plus Elastic and Microsoft KQL where they apply) and live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,445 reports from 149 sources, 666 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
