Summary

CVE-2026-44462 is a medium-severity Incomplete List of Disallowed Inputs (CWE-184) vulnerability in Zed Zed. Its CVSS base score is 6.4 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 36th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SI-10 requires validity checks on inputs, which structurally replaces incomplete deny-lists with complete allow-list or sanitization logic.

Secure SDLC practices directly require complete, positive input validation instead of incomplete denylists.

finds

Security testing can discover missing input checks, but does not prevent the weakness during development.

prevents

Application security requirements can mandate complete input validation rules, but the control itself does not prescribe how to build those rules.

prevents

Secure architecture principles include robust input validation design, yet the control is broader than this single weakness.

prevents

Secure coding standards directly require exhaustive allow-lists or complete deny-lists for inputs, addressing the root cause of incomplete disallowed-input lists.
