——0OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, the webroot admin.php multisite administration page is enabled without an authentication check, reads database configuration from sqlconf.php, and connects to each configured site database. An unauthenticated network actor can obtain site identifiers, database names, site names, exact OpenEMR versions and patch levels, pending upgrade status, and direct login and patient-portal links. This issue is fixed in version 8.3.0.4h CVE-2026-1232088.8 ALT

——0noname Electron desktop build v1.11.2 through v1.11.6.1 contains an unauthenticated local file server with wildcard CORS that allows malicious websites to read, overwrite, or delete installation files. Attackers can send cross-origin requests to /writeFile on localhost port 8089 to overwrite renderer scripts, executing JavaScript with Node.js access as the local user.5h CVE-2026-1232063.7 BAI

——0EdgeChat before 2.20.3 contains a missing authentication vulnerability in the GET /files/:key route that allows unauthenticated or banned users to download decrypted public-channel attachments because canAccessFile() accepts a null user id. Attackers holding an attachment object key can omit or supply an invalid token to retrieve plaintext attachments without a session or channel membership.5h CVE-2026-494077.7 ALT

——0OpenHuman is an open-source agent harness available as a desktop application and Rust library. Before version 0.57.44, its local /ws/dictation WebSocket endpoint lacks client authentication and browser-origin validation. An unauthenticated client, including a malicious web page able to reach the endpoint, can submit audio and trigger resource-intensive speech-to-text processing. Earlier affected versions also accumulate audio in an unbounded buffer, allowing continuous streaming to exhaust process memory. These conditions can degrade performance, exhaust resources, or crash the application. This issue is fixed in version 0.57.44.7h CVE-2026-494056.2 MÉD

——0OpenHuman is an open-source agent harness available as a desktop application and Rust library. Before 0.56.0, the local server exposes the server-sent events endpoint at /events without bearer authentication, permits cross-origin browser access, and uses only a caller-supplied client_id to select WebChannelEvent objects from the process-wide event bus. An unauthenticated local client, or an attacker-hosted web page opened by the victim, can subscribe to another client's stream by supplying a known or guessed identifier; the fixed system identifier makes the proactive-message stream predictable. The exposed events can include complete assistant responses, streamed message content, tool names, tool arguments, and raw tool outputs intended for the local user interface. This issue is fixed in version 0.56.0.5h CVE-2026-493938.4 ALT

——0OpenHuman is an open-source agent harness available as a desktop application and Rust library. Before 0.56.0, the core server protects HTTP POST requests to /rpc with bearer middleware but exposes Socket.IO rpc:request and chat:start handlers without equivalent transport or handler-level authentication. A local unauthenticated client can connect to the Socket.IO namespace and dispatch requests through the same protected controller path that rejects a missing bearer on /rpc. Depending on the selected method, the attacker can read configuration or health data, start agent flows, interact with integrated account APIs, alter local data, or stop and restart services. This issue is fixed in version 0.56.0.7h
