Prior to 1.4.0, the `/groovyScriptTest/registerScript` endpoint accepts user-supplied Groovy script content and passes it to an unsandboxed `Groovy compilation and loading` flow. An authenticated attacker can provide code that is compiled and instantiated on the server, resulting in arbitrary server-side code execution. The issue affects the `rule engine`'s Groovy script test/register flow. This issue is fixed in version 1.4.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9},"cwes":["CWE-78","CWE-94"],"references":["https://github.com/mqttsnet/thinglinks/commit/311ee760dad798f48652722989fcea02349e13a3","https://github.com/mqttsnet/thinglinks/releases/tag/v1.4.0","https://github.com/mqttsnet/thinglinks/security/advisories/GHSA-9vph-5ccx-qp9v"],"products":[],"source":"nvd","synced_at":"2026-10-30T21:45:38.798995037+00:00"},"epss":null,"kev":null,"osv":[],"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).
