Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 allows code injection if the first argument (aka the 'command' argument) to Shell#[] or Shell#test in lib/shell.rb is untrusted data. An attacker can exploit this to call an arbitrary Ruby method.(CVE-2019-16255)

WEBrick::HTTPAuth::DigestAuth in Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 has a regular expression Denial of Service cause by looping/backtracking. A victim must expose a WEBrick server that uses DigestAuth to the Internet or a untrusted network.(CVE-2019-16201)

The web application exposed by the Canon Oce Colorwave 500 4.0.0.0 printer is vulnerable to Stored XSS in /TemplateManager/indexExternalLocation.jsp. The vulnerable parameter is map(template_name). NOTE: this is fixed in the latest version.(CVE-2020-10667)");
