Prior to 2026.3, the `udevices` JSON command handler, `Cmd_UpdateDevices` in `main/WebServerCmds.cpp`, performed no `session.rights` check before invoking a Lua parser script, while its sibling command handlers gate access by role. A low-privilege authenticated user could trigger execution of an existing operator-installed Lua parser script with attacker-controlled input through the `GET /json.htm` endpoint with `type=command` and `param=udevices`. The `script` parameter also lacked a `..` path-traversal guard: `CLuaHandler::executeLuaScript` in `main/LuaHandler.cpp` constructed the filename from the parser directory and the supplied script name before passing it to `luaL_loadfile`. Execution is limited to already-installed valid Lua files; this is not arbitrary code execution, and the advisory states that file-write and upload paths require administrator privileges. This issue is addressed in version 2026.3.\nhttps://www.cve.org/CVERecord?id=CVE-2026-75520https://github.com/domoticz/domoticz/security/advisories/GHSA-8rv5-x8wv-c5c4https://github.com/domoticz/domoticz/commit/73ed0495af6de3309f27cfc0091e803300ab5ccdhttps://github.com/domoticz/domoticz/blob/2026.3/main/WebServerCmds.cpp#L3445-L3451https://github.com/domoticz/domoticz/releases/tag/2026.3https://github.com/domoticz/libwebem/blob/dfe946fa32f4c211662e47ef55b8cedfc50a6a76/include/libwebem/session.h#L10-L17#domoticz#CVE_2026_75520#bot", "url": "https://infosec.exchange/users/cve/statuses/117520924117846040"}, {"timestamp": "2026-10-28T23:17:10.537Z", "date_only": false, "value": "2026-10-28T23:17:10.537", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-75520", "record": "FKIE_CVE-2026-75520", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event"}, {"timestamp": "2026-10-29T16:21:34.310Z", "date_only": false, "value": "2026-10-29T16:21:34.310", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-75520", "record": "FKIE_CVE-2026-75520", "field": "lastModified"}], "metrics": {"as_of": "2026-10-31T17:58:01.239Z", "anchors": {"origin": {"timestamp": "2026-10-28T22:30:59.693Z", "date_only": false, "value": "2026-10-28T22:30:59.693Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-75520", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-10-28T22:30:59.693Z", "date_only": false, "value": "2026-10-28T22:30:59.693Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-75520", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "exploit_publication": null, "exploitation": null, "patch": null}, "vendor_response_time": {"available": false, "missing": ["start", "end"]}, "time_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit_publication": {"available": false, "missing": ["end"]}, "time_to_patch": {"available": false, "missing": ["start", "end"]}, "total_time_to_patch": {"available": false, "missing": ["start", "end"]}, "disclosure_to_patch": {"available": false, "missing": ["end"]}, "time_unpatched": {"available": true, "seconds": 242821.546767, "hours": 67.4504296575, "days": 2.8104345690625, "min_seconds": 242821.546767, "max_seconds": 242821.546767, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-10-28T22:30:59.693Z", "date_only": false, "value": "2026-10-28T22:30:59.693Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-75520", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-10-31T17:58:01.239Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
