{"cve":"CVE-2026-43947","nvd":{"published":"2026-07-21T22:17:01.560","modified":"2026-10-24T19:10:00.127","status":"Deferred","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.","cvss_v4":{"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","score":8.9},"cvss_v3":null,"cwes":["CWE-863"],"references":["https://github.com/frangoteam/FUXA/commit/78534da61a91613712b44bb63c8d7da8c5df5ca4","https://github.com/frangoteam/FUXA/pull/2260","https://github.com/frangoteam/FUXA/releases/tag/v1.3.1","https://github.com/frangoteam/FUXA/security/advisories/GHSA-rg3m-cfq7-g6h6","https://github.com/frangoteam/FUXA/security/advisories/GHSA-rg3m-cfq7-g6h6"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-43947","score":0.00911,"percentile":0.59737,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-rg3m-cfq7-g6h6","url":"https://osv.dev/vulnerability/GHSA-rg3m-cfq7-g6h6","summary":"FUXA Vulnerable to Unauthenticated Remote Code Execution via Script Test Mode Authorization Bypass","modified":"2026-05-27T00:11:27.229833Z","packages":[{"ecosystem":"npm","name":"fuxa-server","purl":"pkg:npm/fuxa-server","ranges":[">=1.3.0 <1.3.1"],"fixed":["1.3.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
