——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 CVE-2026-73578—

——0Missing authorization enforcement in RequestHandler.renderView in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote unauthenticated attacker to bypass the request-map authentication policy for protected views by supplying a crafted _LAST_VIEW_NAME_ value, which is stored as saved-view state in the anonymous session and later rendered without re-applying the original view's authentication requirement, potentially exposing protected views and associated business data. Users are recommended to upgrade to version 24.09.08, which fixes this issue.9h CVE-2026-73577—

——0Incorrect authorization in RequestHandler in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote unauthenticated attacker to bypass the authentication requirement of a protected view by appending it as a path suffix to a public request (e.g., /catalog/control/ListLocales/showPortalPage), causing the servlet to authorize the request based on the public path component while rendering the protected suffix view. Users are recommended to upgrade to version 24.09.08, which fixes this issue.9h CVE-2026-52848—

——17Traccar is an open source GPS tracking system. From 5.1 until 6.15.0, WebModule.java's MediaFilter Guice mapping and WebServer.java's Jetty ResourceServlet assign different routing meanings to path parameters at /api/media/*. An unauthenticated attacker who knows or guesses a device unique ID and media filename can insert a semicolon at the Servlet boundary, bypass MediaFilter's session and device authorization checks, and retrieve the protected media because Jetty still dispatches the noncanonical path to ResourceServlet. The demonstrated impact is read-only disclosure of a protected device media file; depending on the deployment and stored media, this could expose photographs, audio, video, or other uploaded files. The advisory does not establish directory listing, traversal, modification, account takeover, denial of service, or code execution. Reverse proxies that reject or rewrite semicolon path parameters may block the request. This issue is fixed in version 6.15.0.1d CVE-2026-577755.3 MÉD
