Stack-based buffer overflow in Domoticz's MochadTCP component allows an unauthenticated attacker on the local network to corrupt the Domoticz worker thread's stack and potentially achieve arbitrary code execution. The MochadTCP::MatchLine() handler in hardware/MochadTCP.cpp uses strcpy() to copy up to 1028 bytes of network-received data into a fixed 50-byte stack buffer (tempRFSECbuf) across three separate device-type branches, with no length validation whatsoever. No CISA KEV listing and no public exploit code have been identified at time of analysis; exploitation requires adjacency to the Domoticz host's network and benefits from the complete absence of authentication on port 1099.
Stored cross-site scripting in Domoticz's mobile dashboard (all versions prior to 2026.3) allows any authenticated API user to inject persistent JavaScript payloads via Text or Alert subtype device values. The ng-bind-html rendering path applies only an nl2br() newline transform with no HTML escaping, meaning stored payloads execute in every administrator's browser that loads the mobile dashboard. Successful exploitation enables session cookie theft and account takeover; no active exploitation is confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis.
Domoticz versions prior to 2026.1 contain a stored cross-site scripting (XSS) vulnerability in the web interface's Add Hardware and device rename functionality that allows authenticated administrators to inject arbitrary JavaScript or HTML markup. The injected malicious code is stored persistently and executed in the browsers of any users viewing the affected pages, potentially enabling unauthorized session hijacking or malicious actions performed under the victim's privileges. A patch is available from the vendor, and while this requires administrator-level access to exploit, the persistent nature of the vulnerability and user interaction requirement represent moderate real-world risk within administrative environments.
Domoticz 4.10717 has XSS via item.Name. Rated medium severity (CVSS 5.4), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available.
Domoticz before 4.10579 neglects to categorize \n and \r as insecure argument options. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
Domoticz before 4.10578 allows SQL Injection via the idx parameter in CWebServer::GetFloorplanImage in WebServer.cpp. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
