Glexia's Take · Automated analysis
CWE-1093: Excessively Complex Data Representation
Excessively Complex Data Representation represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
Executive Impact
- Other: Reduce Maintainability Increase Analytical Complexity: This issue makes it more difficult to understand or maintain the product, which indirectly affects security by making it more difficult or time-consuming to find and/or fix vulnerabilities. It also might make it easier to introduce vulnerabilities.
- Other: Reduce Performance
Developer Pattern
CWE-1093 is the kind of defect developers can usually prevent with explicit validation, safer framework defaults, and tests that exercise hostile input or unsafe state transitions.
Automation confidence
high confidence from CWE-1093, 4.20.
