Adobe Commerce and Magento Template Injection Vulnerability (CVE-2026-75650)
First seen Sep 9, 2026 · Updated Sep 9, 2026
A critical server-side template injection vulnerability affecting Adobe Commerce and Magento Open Source has been added to CISA's Known Exploited Vulnerabilities catalog, indicating active exploitation in the wild. The flaw allows attackers to inject malicious template elements that are improperly neutralized, resulting in arbitrary code execution on affected servers. Organizations running Adobe Commerce or Magento storefronts must patch by the CISA-mandated due date of September 11, 2026.
Technical Analysis
CVE-2026-75650 stems from improper neutralization of special elements used in a template engine within Adobe Commerce and Magento Open Source, a classic server-side template injection (SSTI) flaw that permits attackers to break out of the template sandbox and execute arbitrary server-side code. Exploitation likely involves crafting malicious input passed to Magento's templating layer (Twig or similar backend rendering), bypassing input sanitization to achieve remote code execution (RCE) without requiring authentication in many configurations. Given its inclusion in CISA KEV with an aggressive 3-day remediation window, active exploitation is confirmed, and threat actors are likely leveraging this for web shell deployment, payment card skimming (Magecart-style attacks), or full server compromise. Organizations that run AI-driven product recommendation engines, chatbots, or RAG-based customer service agents integrated into Magento/Commerce storefronts face risk of credential and API key exposure if agent connectors or backend service accounts are compromised via this RCE, potentially allowing lateral movement into agent orchestration systems.
Affected Systems
Adobe Commerce (all editions) and Magento Open Source installations using vulnerable versions of the template engine; specific version ranges pending Adobe security bulletin confirmation. Both cloud-hosted and on-premises deployments are potentially affected.
Indicators of Compromise
- No specific IOCs publicly disclosed at this time; monitor Adobe Security Bulletin and CISA KEV updates for indicators including malicious template payloads, web shell file names, and anomalous admin panel access logs.
Remediation Steps
- 1
Apply Adobe Security Patch
Immediately apply the official patch or update released by Adobe for Commerce and Magento Open Source addressing CVE-2026-75650.
- 2
Meet CISA Deadline
Federal agencies and critical infrastructure operators must remediate by the September 11, 2026 due date per CISA KEV mandate; all organizations should treat this as urgent.
- 3
Audit Template Inputs
Review and restrict any custom template rendering logic, admin user input fields, and third-party extensions that interact with the templating engine.
- 4
Monitor for Exploitation
Inspect server logs, admin access records, and file integrity for unauthorized changes, web shells, or unexpected outbound connections indicative of post-exploitation activity.
- 5
Rotate Credentials and API Keys
Rotate admin credentials, database passwords, and any API keys used by integrated services (including AI agents or chatbots) that connect to the affected Magento/Commerce instance.
- 6
Isolate Legacy Instances
For instances that cannot be immediately patched, restrict network access, enable WAF rules targeting template injection patterns, and consider taking the storefront offline until remediated.
