CVE-2026-19577 Out-of-bounds read in IPv6 route forwarding when the nexthop neighbor has no link-layer address

netrouteipv6packet in subsys/net/ip/routeipv6.c resolved the nexthop's link-layer address with netnbrgetlladdrnbr-idx without first checking whether the neighbor cache entry actually had a linked link-layer address. An unresolved neighbor carries idx == NETNBRLLADDRUNKNOWN 0xff, and netnbrgetllad...

CVE-2026-19577

The Zephyr RTOS contains an out-of-bounds read vulnerability in the IPv6 route forwarding logic within subsys/net/ip/route_ipv6.c. The net_route_ipv6_packet() function calls net_nbr_get_lladdr() without verifying if a neighbor cache entry has a linked link-layer address. When a neighbor is unreso...

CVE-2026-82754

An Improper Protection of Alternate Path vulnerability in the ash_authentication_oauth2_server Elixir library (versions 0.1.0 through before 0.3.1) causes state-changing OAuth endpoints to be reachable under an unintended URL prefix. The oauth2_server_protocol_routes/1 function in the Phoenix rou...

CVE-2026-58213 NATS Server: MQTT SUBSCRIBE Protocol Injection via Leaf Node/Route Forwarding allows arbitrary NATS command injection

NATS Server is a high-performance server for NATS.io, the cloud and edge native messaging system. Prior to 2.14.1 and 2.12.9, an MQTT client could include protocol control characters in subscription filters that were later forwarded as NATS protocol data to route or leafnode connections, corrupti...

CVE-2026-58213

NATS Server (nats-server) before versions 2.14.1 and 2.12.9 is vulnerable: an MQTT client can include protocol control characters in subscription filters, which are later forwarded as NATS protocol data to route or leafnode connections. This corrupts the forwarded protocol stream and allows injec...
