In JetBrains YouTrack Confluence plugin versions before 1.8.1.3, it was possible to achieve Server Side Template Injection. The attacker could add an Issue macro to the page in Confluence, and use a combination of a valid id field and specially crafted code in the link-text-template field to execute code remotely.
The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
