Technical description

Motor.NET before 0.19.0 contains a denial-of-service vulnerability that allows a remote attacker who can produce records to a consumed topic to crash the service permanently by sending a single crafted record. By setting the content-type header to application/cloudevents+json and omitting required CloudEvent attributes (id, source, type), the attacker triggers an ArgumentException in KafkaMessageConsumer.SingleMessageHandlingAsync that is treated as fatal, causing the host to stop and re-process the same poison record on every restart, resulting in a permanent crash-loop.

——11Motor.NET before 0.19.0 contains an uncaught exception vulnerability in JsonNetDeserializer.Deserialize that allows a remote attacker who can publish to a consumed queue or topic to crash the service permanently by sending structurally valid JSON that does not match the handler's expected type. Attackers can exploit the fact that JsonSerializationException is not caught alongside JsonReaderException and InvalidCastException, causing TypedConsumerService.SingleMessageConsumeAsync to treat the error as CriticalFailure and call StopApplication, which combined with the unacknowledged message being redelivered on restart results in a permanent crash-loop.1d CVE-2026-1123307.5 HIG

——15Motor.NET before 0.19.0 contains a denial of service vulnerability that allows a remote attacker who can publish to a consumed queue to crash the service permanently by sending a message with crafted cloudEvents headers. Attackers can supply an invalid cloudEvents:motorversion, a single double-quote header value, or an unparsable typed attribute such as cloudEvents:time to trigger an unhandled exception in ExtractCloudEvent that is treated as fatal, causing the application to stop and the unacknowledged message to be redelivered on restart, resulting in a permanent crash-loop.21h CVE-2026-1096198.1 HIG

——28PHP has various global state that temporarily points into request memory. In some scenarios, global state may not be correctly reset, or may be repopulated after being reset. The global state may then refer to request memory even after it has been freed. Subsequent requests may read or branch on this stale state before it is fully initialized. Multiple strategies can trigger this condition and produce remote code execution (RCE).1d CVE-2026-1096189.8 CRI

——29PHP uses longjmp() for out-of-memory (OOM) errors to exit the current context and abort handling of the request. Some contexts may not properly account for this scenario and leave request memory in an uninitialized state before performing an allocation. The subsequent request cleanup procedure may read or branch on this memory. Multiple OOM strategies can consistently trigger this condition and lead to remote code execution (RCE).1d CVE-2026-1039367.5 HIG

——13libp2p is a JavaScript implementation of the libp2p networking stack. Prior to 6.0.28, the @libp2p/webrtc webRTCDirect() Node.js listener processes unauthenticated STUN Binding Requests before PeerId authentication, Noise, muxing, protocol negotiation, connection creation, or connection-manager admission. The listener in packages/transport-webrtc/src/private-to-public/utils/stun-listener.ts forwards the packet-controlled request.ufrag into DirectRTCPeerConnection.setLocalDescription, where the value is reused as an ICE password without validating its required length and character set. A short credential causes node-datachannel or libdatachannel to raise an uncaught native invalid_argument and abort the process with SIGABRT, allowing a single remote UDP packet to deny service. The confirmed impact is process termination only, with no demonstrated memory corruption, code execution, browser impact, confidentiality impact, integrity impact, or connection-limit bypass. This issue is fixed in version 6.0.28.8d CVE-2026-854735.3 MED

——7The auth0/java-jwt library may terminate a thread if it receives a JWT with a timestamp claim (exp, nbf, iat) containing an out-of-range value. The condition occurs during token parsing, prior to signature verification. Repeated requests of this nature may lead to degraded availability of the affected service.8d
