  - A Reflected Cross Site Scripting flaw was found in all pki-core 10.x.x versions module from the pki-core     server due to the CA Agent Service not properly sanitizing the certificate request page. An attacker could     inject a specially crafted value that will be executed on the victim's browser. (CVE-2019-10146)

  - A vulnerability was found in all pki-core 10.x.x versions, where the Key Recovery Authority (KRA) Agent     Service did not properly sanitize recovery request search page, enabling a Reflected Cross Site Scripting     (XSS) vulnerability. An attacker could trick an authenticated victim into executing specially crafted     Javascript code. (CVE-2019-10179)

  - A Reflected Cross Site Scripting vulnerability was found in all pki-core 10.x.x versions, where the pki-ca     module from the pki-core server.
