CVE-2019-19376 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. In Octopus Deploy before 2019.10.6, an authenticated user with TeamEdit permission could send a malformed Team API request that bypasses input validation and causes an application level denial of service condition. (The fix for this was also backported to LTS 2019.9.8 and LTS 2019.6.14.). EPSS estimates a 0.99% chance of exploitation in the next 30 days.
