CVE-2015-5216: Ipsilon-Project Ipsilon

Medium severity, CVSS 6.1. EPSS: 1.1% chance of exploitation in the next 30 days.

The Identity Provider (IdP) server in Ipsilon 0.1.0 before 1.0.1 does not properly escape certain characters in a Python exception-message template, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via an HTTP response.

Affected products

• Ipsilon-Project Ipsilon: from 0.1.0, before 1.0.1 (fixed in 1.0.1)
