As a result, the intended structure of the message is not preserved.","Improper encoding or escaping can allow attackers to change the commands that are sent to another component, inserting malicious commands instead.\nMost products follow a certain protocol that uses structured messages for communication between components, such as queries or commands. These structured messages can contain raw data interspersed with metadata or control information. For example, \"GET \u002Findex.html HTTP\u002F1.1\" is a structured message containing a command (\"GET\") with a single argument (\"\u002Findex.html\") and metadata about which protocol version is being used (\"HTTP\u002F1.1\").\nIf an application uses attacker-supplied inputs to construct a structured message without properly encoding or escaping, then the attacker could insert special characters that will cause the data to be interpreted as control information or metadata. Consequently, the component that receives the output will perform the wrong operations, or otherwise interpret the data incorrectly.","Draft","Class","Simple",false,[],{"title":75,"metaDescription":76,"keywords":77,"canonicalUrl":78,"structuredData":79},"What is CVE-2026-105244?
