{"id":"CVE-2026-43947","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-43947","generatedAt":"2026-10-28T07:04:43.869Z","title":"Version 1.3.0 has an unauthenticated Remote Code Execution vulnerability when `secureEnabled` is set to `true`.","description":"FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Version 1.3.0 has an unauthenticated Remote Code Execution vulnerability when `secureEnabled` is set to `true`. The `POST /api/runscript` endpoint checks authorization against the stored script's permission by ID, but when `test: true` is set in the request, it compiles and executes attacker-supplied code instead of the stored script's code. An unauthenticated attacker who knows a valid script ID and name may execute arbitrary code via test mode if at least one server-side script exists and is accessible without restrictive permissions. Script IDs and names can be obtained through the unauthenticated information disclosure in `GET /api/project` (reported separately). The only prerequisite is that at least one server-side script exists in the project. Version 1.3.1 fixes the issue.","published":"2026-07-21T22:17:02.000Z","lastModified":"2026-10-24T19:10:00.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"4.0","score":8.9,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-863"],"affected":[],"epss":{"score":0.00911,"percentile":0.5981,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.91%).
