Summary

CVE-2026-12370 is a high-severity Improper Neutralization of Special Elements Used in a Template Engine (CWE-1336) vulnerability. Its CVSS base score is 7.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Template Injection (T1221); ranked in the top 27% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and static analysis can discover missing neutralization of template directives.

Security engineering principles require use of safe templating APIs and proper escaping of external input.

Input validation rejects or sanitizes untrusted data before it reaches the template engine, stopping injection of special syntax.

PR.PS-06 partial match
prevents

Secure SDLC practices directly require proper input neutralization in template engines to prevent injection.

prevents

Secure development life cycle mandates input validation and sanitization that directly prevents template-injection weaknesses.

prevents

Application security requirements explicitly call for neutralizing special elements in template engines.

prevents

Secure architecture principles reduce the likelihood of unsafe template processing but do not prescribe specific neutralization techniques.

prevents

Secure coding standards require proper escaping or sandboxing of template directives, directly mitigating CWE-1336.

finds

Security testing can detect template-injection flaws but does not itself implement neutralization controls.
