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

CVE-2026-75650 is an improper neutralization of special elements used in a template engine vulnerability affecting Adobe Commerce and Magento Open Source. In plain terms, the product does not safely handle certain special elements when processing templates, which can let an attacker run arbitrary code on a vulnerable system. For IT and security teams, that matters because Adobe Commerce and Magento often sit on internet-facing storefronts and admin paths that handle customer, order, and payment-related data; successful code execution can lead to full application compromise. Confirm exact product editions, fixed releases, and deployment notes only against the vendor advisory.

CISA describes the issue as one that could allow arbitrary code execution. Public detail in the record does not document known ransomware use. Treat exposure and internet reachability as primary risk factors and follow your organization’s patch prioritization, including applicable federal guidance such as BOD 26-04 where it applies.

How it works

The weakness is tracked as CWE-1336: improper neutralization of special elements used in a template engine. Template engines combine fixed layout with dynamic data or logic. When special elements that the engine treats as instructions or markup are not correctly neutralized, attacker-controlled input can be interpreted as template logic rather than plain data.

At a high level, an attacker who can influence content that is later rendered or compiled by the template engine may inject constructs the engine executes. In e-commerce platforms of this class, that often means paths where user- or merchant-supplied content, configuration, or other inputs flow into templating. The CISA summary states the outcome can be arbitrary code execution. Do not assume a specific entry point, authentication requirement, or payload format from this write-up; those mechanics must be taken from the vendor advisory and your own threat model. Exploitation of template-injection style flaws commonly aims at web-shell placement, credential theft, or lateral movement from the application host.

Am I affected? How to find it in your systems

Adobe Commerce and Magento typically run as PHP-based storefront and admin applications on web tiers, often behind load balancers or CDNs, with associated databases, caches, and job workers. Inventory every instance: production, staging, and development; on-premises, hosted, and cloud commerce deployments; and any agency- or partner-managed stores.

• Build an asset list from CMDB, deployment pipelines, container images, and DNS or certificate inventories for known storefront hostnames.
• Record product line (Adobe Commerce vs Magento Open Source), version, and patch level from admin about pages, composer lock files, or vendor support portals—then compare only to the versions the vendor lists as affected or fixed.
• Note whether admin panels, APIs, and template- or content-related features are internet-exposed; map trust boundaries for content editors and integrations that can supply template-related input.
• Review application, web server, and WAF logs for unusual template errors, unexpected dynamic code paths, new PHP or shell processes spawned by the web user, outbound connections from app hosts, and sudden admin or file-integrity changes. Specific exploit signatures are not provided in the given facts; tune detection after reading the advisory.

If version or configuration detail is unclear, treat the instance as potentially affected until confirmed against the vendor advisory.

How to remediate

Patch first. Apply the updates and mitigations Adobe publishes for this CVE, in the order and for the editions the advisory specifies. Validate in a non-production environment when possible, then roll out under change control with rollback plans.

• After patching, verify version strings and that required configuration changes from the advisory are present.
• For this weakness class, reduce how untrusted input reaches template rendering: tighten who can edit templates, CMS blocks, email templates, and related content; enforce least privilege on admin roles; and disable unused template or customization features if the vendor documents that option.
• Harden the application host: run the web process with minimal privileges, keep file permissions strict on template and code directories, enable file-integrity monitoring, and isolate the storefront from internal networks and secrets stores.
• Rotate credentials and API keys that the application could have exposed if you suspect prior compromise, and re-check scheduled tasks, installed modules, and writable paths for unauthorized changes.
• Federal and regulated stakeholders should apply mitigations per vendor instructions, evaluate internet exposure, and align with BOD 26-04 prioritization and any applicable forensics triage requirements; discontinue use if mitigations cannot be applied and risk is unacceptable.

If you can't patch immediately

Compensating controls reduce but do not eliminate risk until the vendor fix is in place.

• Segment storefront and admin hosts; restrict admin and management interfaces to VPN or allowlisted networks.
• Place a WAF or reverse proxy in front of the application with rules aimed at template-injection and anomalous request patterns for this product class; treat this as virtual patching only until the real update is applied, and tune to avoid breaking legitimate catalog and CMS traffic.
• Temporarily disable or tightly restrict features that accept rich template or untrusted content if business process allows and the vendor does not prohibit that approach.
• Increase monitoring: alert on new files under web roots, unexpected process execution by the application user, privilege changes, and unusual outbound traffic; retain logs for incident response.
• Reduce internet exposure of nonessential endpoints and third-party modules until patched.

Reassess daily until the official remediation is deployed. Confirm any temporary workaround against the vendor advisory so you do not rely on incomplete measures.

If your data may have been exposed

Actively exploited code-execution flaws on commerce platforms can lead to breaches involving customer PII, order history, and integrated payment or marketing systems. The facts for this CVE do not document ransomware use, but absence of that note is not proof of safety. If compromise is suspected, isolate affected hosts, preserve logs and disk evidence, rotate secrets, and follow your incident response plan and any required forensics triage process. As a routine check, you can run a free exposure scan of your email addresses against known breach datasets to see whether those identities already appear in public breach collections, then prioritize password resets and monitoring accordingly.
