Weakness Types

What is a Code Injection Vulnerability?

The software constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.

CVE-2026-44006 has been classified to as a Code Injection vulnerability or weakness.

Improper Control of Dynamically-Identified Variables

The software does not properly restrict reading from or writing to dynamically-identified variables. Many languages offer powerful features that allow the programmer to access arbitrary variables that are specified by an input string. While these features can offer significant flexibility and reduce development time, they can be extremely dangerous if attackers can modify unintended variables that have security implications.
