What is CWE-1114: Inappropriate Whitespace Style?

CWE-1114: Inappropriate Whitespace Style is a Common Weakness Enumeration (CWE) entry maintained by MITRE. The source code contains whitespace that is inconsistent across the code or does not follow expected standards for the product.

What are the security consequences of Inappropriate Whitespace Style?

If exploited, CWE-1114 (Inappropriate Whitespace Style) it can compromise Other, leading to outcomes such as Increase Analytical Complexity and Reduce Maintainability.

Which programming languages are affected by Inappropriate Whitespace Style?

CWE-1114 commonly affects Not Language-Specific. Note that weaknesses are often language-agnostic patterns, so secure coding practices apply broadly.

What are real-world examples of Inappropriate Whitespace Style?

MITRE documents real CVEs mapped to CWE-1114, including CVE-2014-1266. You can look up the full details of each CVE, including CVSS scores and remediation guidance, on our CVE Lookup tool.

What is the difference between a CWE and a CVE?

A CWE (Common Weakness Enumeration) like CWE-1114 describes a category of software weakness — the underlying flaw type. A CVE (Common Vulnerabilities and Exposures) identifies a specific, real-world vulnerability in a particular product. In short, a CWE is the kind of mistake, and a CVE is an instance of that mistake being found in software.

Verify controls for CWE-1114 with SSDF evidence

Use NIST SSDF verification and vulnerability-response practices to detect CWE-1114, Inappropriate Whitespace Style, throughout the product lifecycle. Derive review questions, static or dynamic checks, and negative tests from the CWE's causal behavior; define the components and lifecycle stages each check covers; and retain findings with enough evidence to distinguish the root cause from symptoms and impacts. Track escapes and false negatives, then improve the verification plan after every confirmed occurrence.

Make elimination of CWE-1114 a product outcome

Apply CISA's Secure by Design principle of taking ownership of customer security outcomes to CWE-1114, Inappropriate Whitespace Style. Put the weakness in the product threat model and security roadmap, fund class-level design and platform changes, prefer safe defaults and reusable guardrails, and publish measurable progress. Do not transfer the primary burden to customer configuration when the manufacturer can remove or contain the root cause in the product.

Apply precise root-cause mapping to CWE-1114

Apply MITRE's full root-cause mapping guidance when using CWE-1114, Inappropriate Whitespace Style. Separate weakness language from attacker prerequisites and technical impact, check the entry's abstraction and vulnerability-mapping notes, and prefer the most specific Base or Variant supported by the evidence. Record the rejected alternatives and require an independent review before the mapping is used for remediation trends or program metrics.

Validate CWE-1114 with root-cause mapping checks

Apply MITRE's root-cause mapping quick tips to CWE-1114, Inappropriate Whitespace Style. Confirm the finding describes the causal weakness rather than an impact or attack pattern, compare the abstraction and mapping notes with plausible alternatives, and have a second reviewer challenge the selection. Preserve the evidence and reasoning so recurring defects can be measured against one consistent identifier.
