Description

LimeSurvey through 6.17.10 and 7.0.4 contains a server-side request forgery vulnerability in the REST API survey template endpoint that allows authenticated users to cause the server to issue arbitrary HTTP requests by supplying a manipulated Host header. Attackers can exploit the unsanitized use of the HTTP Host header in the getTemplateData() function to reach internal network services, cloud metadata endpoints, and extract sensitive credentials such as IAM tokens from instance metadata services.
