What is CVE-2021-42560?

In CALDERA version 2.9.0, a vulnerability exists that involves the Debrief plugin, which improperly handles base64 encoded 'SVG' parameters during PDF generation. The unsafe parsing of these SVG documents creates a pathway for potential exploitation via XML External Entity (XXE) attacks. This could lead to severe consequences, including file exfiltration, server-side request forgery, and out-of-band data exfiltration. Security measures should be taken to mitigate this risk.
