CVE-2024-45053: Ethyca Fides

High severity, CVSS 7.2. EPSS: 1.3% chance of exploitation in the next 30 days.

Fides is an open-source privacy engineering platform. Starting in version 2.19.0 and prior to version 2.44.0, the Email Templating feature uses Jinja2 without proper input sanitization or rendering environment restrictions, allowing for Server-Side Template Injection that grants Remote Code Execution to privileged users. A privileged user refers to an Admin UI user with the default `Owner` or `Contributor` role, who can escalate their access and execute code on the underlying Fides Webserver container where the Jinja template rendering function is executed. The vulnerability has been patched in Fides version `2.44.0`. Users are advised to upgrade to this version or later to secure their systems against this threat. There are no workarounds.

Affected products

• Ethyca Fides: from 2.19.0, before 2.44.0 (fixed in 2.44.0)
