CVE-2015-5215: Ipsilon-Project Ipsilon

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

The default configuration of the Jinja templating engine used in the Identity Provider (IdP) server in Ipsilon 0.1.0 before 1.0.1 does not enable auto-escaping, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via template variables. NOTE: This may be a duplicate of CVE-2015-5216. Moreover, the Jinja development team does not enable auto-escape by default for performance issues as explained in https://jinja.palletsprojects.com/en/master/faq/#why-is-autoescaping-not-the-default.

Affected products

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