Vulnerability description
DayBreach CVE AI Research
CVE-2026-76784 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
Multiple TP-Link Kasa smart home devices contain insufficient cryptographic protections in the local device communication protocol. An adjacent network attacker may intercept, replay or forge locally exchanged control messages, potentially resulting in unauthorized device control. Successful exploitation could allow an attacker to manipulate the operational state of an affected device, resulting in unauthorized state changes, disruption of normal device functionality or a denial-of-service condition.
