Summary

CVE-2026-6984 is a low-severity Incomplete Filtering of Special Elements (CWE-791) vulnerability. Its CVSS base score is 2.0 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Template Injection (T1221); ranked at the 22th percentile by exploit likelihood (below the median); 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 SI-10 (Information Input Validation) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

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

SI-10 Information Input Validation good match

Input validation directly requires complete filtering of special elements on received data before further processing or forwarding.

SA-8 Security and Privacy Engineering Principles partial match

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

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require complete input filtering and sanitization to prevent this weakness.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development and acceptance can detect incomplete filtering but does not itself implement the filtering.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle processes include validation activities that reduce the likelihood of CWE-791 but do not specify the control itself.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for input validation and sanitization that directly mitigates incomplete special-element filtering.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure system architecture and engineering principles require defensive design patterns that prevent unfiltered data from reaching downstream components.

A.8.28 Secure coding partial match
prevents

Secure coding standards mandate complete filtering and escaping of special elements, directly eliminating CWE-791.
