CVE-2020-5304 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. The dashboard in WhiteSource Application Vulnerability Management (AVM) before version 20.4.1 allows Log Injection via a %0A%0D substring in the idp parameter to the /saml/login URI. This closes the current log and creates a new log with one line of data. EPSS estimates a 1.00% chance of exploitation in the next 30 days.
