Description
countly-server is the server-side part of Countly, a product analytics solution. Prior to 24.05.50 and 25.03.44, public image and screenshot routes implemented in frontend/express/app.js, plugins/star-rating/frontend/app.js, and plugins/dashboards/frontend/app.js concatenate attacker-controlled wildcard paths without containment validation. On deployments using the local filesystem backend, an unauthenticated request can traverse outside the intended asset directories and reach getStats or getStream in api/utils/countlyFs.js, allowing arbitrary readable server files to be disclosed. The affected routes include /appimages/*, /memberimages/*, */screenshots/*, /star-rating/images/*, and /dashboards/images/screenshots/*. This issue is fixed in versions 24.05.50 and 25.03.44.
