Common Weakness Enumeration

CWE-793

Weakness Allowed

Only Filtering One Instance of a Special Element

Abstraction: Variant · Status: Incomplete

The product receives data from an upstream component, but only filters a single instance of a special element before sending it to a downstream component.

Incomplete filtering of this nature may be location-dependent; e.g., only the first or last element is filtered.

Mapping guidance

This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.

Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
