Technical 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.

———Helical Insight through 7.0.0 contains a path traversal vulnerability that allows authenticated viewers to read files outside the solution directory via the path parameter of /getExternalResource. Attackers can supply parent-directory segments to read any readable file with an allowed extension such as js, json, or html, bypassing per-resource access control.6h CVE-2026-1116185.3 MED

———countly-server is the server-side part of Countly, a product analytics solution. Prior to 24.05.50 and 25.03.44, the authenticated data-migration deletion route in plugins/data_migration/api/api.js passes the user-controlled exportid to clean_up_data without path validation. plugins/data_migration/api/data_migration_helper.js concatenates that identifier into a path resolved outside the intended import directory and calls remove recursively, allowing an application administrator or user with migration permission to delete writable files or directory trees and cause data loss or service disruption. This issue is fixed in versions 24.05.50 and 25.03.44.5h CVE-2026-1077776.5 MED

—

———Improper path containment check in ikus060 rdiffweb 7.1.1 allows an authenticated user to cause the browse, restore, history and delete operations to resolve to a path outside the repository being operated on, via a percent-encoded traversal sequence (%2e%2e) in the request path, because the containment check uses a string prefix comparison (startswith) instead of a filesystem path boundary check. The target must be a sibling path whose name begins with the repository path, and the user already hold permissions on it; the issue can mislead a user into operating on, or deleting, data other than the repository displayed5h CVE-2026-937676.5 MED

—

———The Tainacan plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 1.3.0 via the 'guid' parameter parameter. This makes it possible for authenticated attackers, with subscriber-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information. This vulnerability is exploitable only when the uploads/tainacan directory does not exist on the server, as this condition causes realpath() to return false, collapsing the base path to an empty string and rendering the containment check ineffective.9h
