Description
HedgeDoc is an open source, real-time, collaborative, markdown notes application. Prior to 1.10.6, files served below the /uploads/ endpoint did not use a more strict security-policy. This resulted in a too open Content-Security-Policy and furthermore opened the possibility to host malicious interactive web content (such as fake login forms) using SVG files. This vulnerability is fixed in 1.10.6.
