One of the stored XSS issues – CVE-2022-1175 – allowed attackers to inject HTML in notes because of “improper neutralization of user input”.

Both XSS vulnerabilities notched a CVSS score of 8.7. Affected versions are 14.7.7 back to 14.4 for CVE-2022-1175 and back to 8.3 for CVE-2022-1190; and all 14.8 versions up to 14.8.5 plus all 14.9 versions up to 14.9.2 for both CVEs.
