Technical description

4gaBoards is a boards system for realtime project management. Prior to 3.3.9, 4gaBoards allows any authenticated user to enumerate account information for every user through GET /api/users and retrieve arbitrary accounts through GET /api/users/:id. The users/index and users/show actions rely only on the default is-authenticated policy in server/config/policies.js, and server/api/controllers/users/index.js returns the result of sails.helpers.users.getMany() without requester-specific authorization or response sanitization. Responses expose email, phone, organization, name, isAdmin, ssoGoogleEmail, ssoGithubEmail, and other SSO-linked email fields, including data for administrators. This enables instance-wide user enumeration, privacy loss, and targeted phishing reconnaissance. This issue is fixed in version 3.3.9.

———Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.20, the default-open GET /log WebSocket route configured in config/node/api.yaml and registered by network/api/api.go does not require authentication. The first client message is parsed as a logger Profile in network/api/logs/logSender.go and applied process-wide through Profile.Apply, allowing a remote client to change global log levels and formatting options until the connection closes. The same connection is registered as a log observer and can receive live process logs. An attacker can suppress normal logs, increase verbosity, distort operator visibility, and access operational information without credentials. This issue is fixed in version 1.7.20.10h CVE-2026-90899—

——0Joomla Extension - joomshaper.com - Unauthenticated PII Exposure via IDOR in Guest Checkout in Easy Store extension 1.0.0-3.0.0 - The checkout.searchGuestUser endpoint allowed querying guest checkout records solely by supplying an email address. The server returned complete shipping details (full name, phone number, street address, city, postal code, and country) directly from the #__easystore_guests table with no authentication, session validation, or ownership checks. An unauthenticated attacker could iterate through email lists to enumerate guest customers and harvest sensitive Personally Identifiable Information (PII). Resolved by removing the unauthenticated server-side guest lookup endpoint entirely and migrating autofill functionality to client-side localStorage protected by explicit user consent.10h
