CVE-2026-41582
countly-server: Unauthenticated Path Traversal via Public Image and Screenshot Routes Leads to Read Internal Files
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.
