Weakness
CWE-75: Failure to Sanitize Special Elements into a Different Plane (Special Element Injection)
The product does not adequately filter user-controlled input for special elements with control implications.
How to prevent it
- 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.
