CVE-2026-62960 Git for Windows: Server-advertised bundle-uri can trigger outbound SMB callbacks via UNC and file:// paths on Windows

Git for Windows is the Windows port of Git. Prior to 2.55.0.windows.4, a malicious remote Git server can advertise a bundle URI that reaches transportgetremotebundleuri, fetchbundleuriinternal, and copyuritofile in bundle-uri.c during clone or fetch when transfer.bundleuri=true. Non-HTTPS values...

CVE-2026-62960

Git for Windows prior to 2.55.0.windows.4 is vulnerable to a security bypass in bundle-uri.c . When transfer.bundleuri=true, a malicious remote Git server can advertise a bundle URI processed by transport_get_remote_bundle_uri(), fetch_bundle_uri_internal(), and copy_uri_to_file(). Non-HTTP(S) va...

CVE-2026-58254

A flaw was found in NATS Server. Message trace destination checks, which ensure that trace events are sent to authorized subjects, were not consistently applied to messages originating from leafnode connections. This inconsistency allows a leafnode operator to bypass these checks and send trace...

CVE-2026-58214

A flaw was found in NATS Server, a high-performance messaging system. An authenticated MQTT Message Queuing Telemetry Transport client could bypass security permissions by subscribing to an internal subject family. This unauthorized access allows the client to view sensitive MQTT Quality of Servi...

CVE-2026-58211

A flaw was found in NATS Server, a high-performance messaging system. This vulnerability allows a client to bypass normal authentication and connection restrictions by registering as a "noauthuser" through a specific parser path. This occurs when the client's initial operation is not a standard...

CVE-2026-58209

A flaw was found in NATS Server. This vulnerability allows for unauthorized information disclosure where MQTT messages, intended to be denied based on subscription rules, are still delivered to subscribers. This occurs because the server's delivery paths do not consistently recheck the original...

CVE-2026-58213

A flaw was found in NATS Server. An authenticated MQTT client could exploit this by embedding protocol control characters within subscription filters. These characters would then be forwarded as NATS protocol data to route or leafnode connections, leading to the corruption of the protocol stream...
