CWE-91XML Injection (aka Blind XPath Injection)

Abstraction: Base · CVEs in our corpus: 134

The product does not properly neutralize special elements that are used in XML, allowing attackers to modify the syntax, content, or commands of the XML before it is processed by an end system.

Within XML, special elements could include reserved words or characters such as "<", ">", """, and "&", which could then be used to add new data or modify XML syntax.
