CVE-2026-5855

Contiki-NG: LwM2M TLV parser in os/services/lwm2m/lwm2m-tlv.c (function lwm2m_tlv_read) ignores the caller’s buffer length and may read up to six bytes without bounds checks. The engine loop continues while bytes remain, so a crafted CoAP WRITE to any LwM2M endpoint whose final TLV supplies exact...

Apache Camel 4.14.x < 4.14.6 / 4.15.x < 4.18.1 RCE (CVE-2026-33453)

The version of Apache Camel on the remote host is 4.14.x prior to 4.14.6 or 4.15.x through 4.18.x prior to 4.18.1. It is, therefore, affected by a remote code execution vulnerability: - The camel-coap component maps incoming CoAP request URI query parameters directly into Camel Exchange In messag...

Apache Camel: camel-coap: Apache Camel camel-coap: Remote code execution via CoAP URI query parameter injection

A flaw was found in Apache Camel's camel-coap component. An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted CoAP Constrained Application Protocol UDP User Datagram Protocol packet. The camel-coap component improperly processes URI query parameters,...

Improperly Controlled Modification Of Dynamically-Determined Object Attributes

Apache Camel is vulnerable to Improperly Controlled Modification of Dynamically-Determined Object Attributes. The vulnerability is due to lack of header filtering when mapping CoAP query parameters to message headers, which allows an attacker to inject malicious headers and execute arbitrary...
