A flaw was found in pki-core. An attacker who has successfully compromised a key could use this flaw to renew the corresponding certificate over and over again, as long as it is not explicitly revoked. The highest threat from this vulnerability is to data confidentiality and integrity.

It was found that the Token Processing Service (TPS) did not properly sanitize the Token IDs from the "Activity" page, enabling a Stored Cross Site Scripting (XSS) vulnerability. An unauthenticated attacker could trick an authenticated victim into creating a specially crafted activity, which would execute arbitrary JavaScript code when viewed in a browser. All versions of pki-core are believed to be vulnerable.
