Shibboleth Service Provider before 3.2.1 allows content injection because template generation uses attacker-controlled parameters.

Weakness

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
