  "title": "Stored cross-site scripting in Countly Server feedback uploads",
  "summary": "Countly Server versions before 24.05.50 and 25.03.44 mishandle files uploaded through the star-rating feedback feature. A non-global application administrator can cause active content to be retained and later run in a global administrator's Countly session when that administrator views a feedback preview. This requires an attacker with the applicable application-administrator access and a global administrator to open the preview.",
  "mitigation": "Upgrade countly-server to 24.05.50 or 25.03.44. Until upgrading, restrict non-global application administrator access and avoid opening untrusted feedback previews.",
