Glexia's Take
CWE-75: Failure to Sanitize Special Elements into a Different Plane (Special Element Injection)
Failure to Sanitize Special Elements into a Different Plane (Special Element Injection) represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
Executive Impact
- Integrity,Confidentiality,Availability: Modify Application Data,Execute Unauthorized Code or Commands
Developer Pattern
CWE-75 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.

Developer And Remediation Guidance
How teams prevent and detect this weakness
Causes
- Missing validation
- Unsafe defaults
- Insufficient authorization or memory-safety invariant
Remediation
- Requirements: Programming languages and supporting technologies might be chosen which are not subject to these issues.
- Implementation: Utilize an appropriate mix of allowlist and denylist parsing to filter special element syntax from all input.
Detection
- Code review
- SAST
- DAST
- Focused regression tests
