CVE-2026-9160 Overview
CVE-2026-9160 is a code injection vulnerability in the Arma Digital Media Inc. Website Template product. The flaw stems from improper neutralization of special elements used in a template engine, classified under [CWE-1336]. Attackers can inject template directives that the engine evaluates as code. Exploitation requires user interaction and delivers a limited integrity impact. The vendor was contacted about this disclosure but did not respond, leaving affected deployments without a vendor patch at publication time. The issue affects Website Template builds through 11092026.
Critical Impact
Attackers can inject template syntax that the server-side engine evaluates, enabling code injection with limited integrity impact when a user interacts with a crafted request.

Technical Details for CVE-2026-9160
Vulnerability Analysis
The vulnerability resides in how the Website Template product processes user-controlled input passed to its template engine. The application fails to neutralize special elements that carry meaning to the template parser. As a result, attacker-controlled strings are interpreted as template expressions rather than literal text. This class of flaw, tracked as Server-Side Template Injection under [CWE-1336], allows adversaries to influence rendered output and, depending on the engine, execute logic beyond simple string interpolation.
The reported impact is limited to integrity. Confidentiality and availability are not directly affected according to the assessed vector. Exploitation requires a user to interact with an attacker-supplied link or input, which typically means clicking a crafted URL or submitting a prepared form.
Root Cause
The root cause is missing or insufficient sanitization of template metacharacters before they reach the engine's evaluation stage. Input that should be treated as data is concatenated or embedded into template contexts where the parser expects trusted directives. The engine then evaluates attacker input as part of the template expression.
Attack Vector
The attack is delivered over the network and requires user interaction. An attacker crafts a request containing template syntax and lures a victim to trigger it. The server renders the template, evaluates the injected expression, and returns manipulated output. Because no privileges are required, unauthenticated attackers can stage the payload. Refer to the Siber Güvenlik Notification TR-26-1083 for the coordinated disclosure record.
No verified proof-of-concept code is available. The exact injection surface and payload syntax depend on the underlying template engine used by the Website Template product, which is not disclosed in public references.
Detection Methods for CVE-2026-9160
Indicators of Compromise
- HTTP request parameters or path segments containing template metacharacters such as {{, }}, ${, <%, or %>.
- Anomalous responses where request parameters appear evaluated rather than reflected literally.
- Outbound connections or process spawns originating from the web application worker following crafted requests.
Detection Strategies
- Inspect web server and application logs for URL parameters and POST bodies containing template delimiter sequences.
- Correlate suspicious request patterns with subsequent child-process activity from the web server user.
- Deploy web application firewall rules that flag template syntax in untrusted input fields.
Monitoring Recommendations
- Enable verbose logging on the Website Template application to capture rendered template contexts.
- Monitor for unexpected file writes, script execution, or configuration changes in the web root.
- Alert on egress traffic from the web tier to unfamiliar destinations after user-driven page loads.
How to Mitigate CVE-2026-9160
Immediate Actions Required
- Inventory deployments of Arma Digital Media Website Template and identify builds at or before 11092026.
- Restrict user input reaching template rendering paths through input allow-lists on the perimeter.
- Isolate affected instances behind a reverse proxy that strips or rejects template delimiter sequences.
- Advise users to avoid clicking untrusted links pointing to affected sites until mitigation is in place.
Patch Information
The vendor did not respond to the disclosure attempt, and no official patch is referenced in the advisory. Operators should track the Siber Güvenlik Notification TR-26-1083 for updates and contact the vendor directly for remediation guidance.
Workarounds
- Enforce strict input validation that rejects template metacharacters in query strings, form fields, and headers.
- Render user-supplied data using context-aware escaping instead of passing it into template contexts.
- Run the application under a low-privilege service account to limit the blast radius of injected expressions.
- Deploy WAF signatures targeting Server-Side Template Injection payloads until a vendor fix is available.
