An operator or attacker with API access could register a service using a crafted name containing HTML elements (such as `<iframe src=\"...\">`). If an administrative web UI rendered the unescaped service name, arbitrary script execution could occur in the context of the user's browser session.\n\n### PoC\n1. Create an external service JSON definition with a filename containing an XSS payload, e.g. `<iframe src=\"javascript:alert`1337`\">.json` inside a ZIP archive.\n2. In external service creation, upload the ZIP and provide the matching service name: `<iframe src=\"javascript:alert`1337`\">`.\n3. Upon service registration, the unescaped name executes when rendered in the UI context.\n\n### Impact\nSelf-XSS / Stored XSS leading to potential session token leakage or unauthorized actions in the context of the affected user's browser session.\n\n### Remediation & Patches\n- **Upgrade to eKuiper >= 2.4.0**: Strict alphanumeric identifier validation (`validate.ValidateID`) is now enforced on all external service creation and update endpoints, rejecting invalid characters.\n\n### Workarounds\n- Protect eKuiper management endpoints (`POST /services`) with authentication and network-level firewalls.\n\n### Credits\n- Reported by Alexey Kosmachev, Bi.Zone (@TheMostKnown)","state":0,"publishedAt":"2026-09-09T17:56:22+00:00","modifiedAt":"2026-09-17T17:40:43.0364918+00:00","affected":[{"ecosystem":"Go","name":"github.com/lf-edge/ekuiper/v2","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2.4.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"LOW"}],"references":["https://github.com/lf-edge/ekuiper/security/advisories/GHSA-g8rh-fjm6-h2h9","https://github.com/lf-edge/ekuiper","https://github.com/lf-edge/ekuiper/releases/tag/v2.4.0"],"sourceUrl":"https://github.com/advisories/GHSA-g8rh-fjm6-h2h9","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-g8rh-fjm6-h2h9","identifiers":["GHSA-g8rh-fjm6-h2h9","CVE-2025-24978","GO-2026-6446"]},"retained":false,"historicalAffected":[]},{"revision":"903ab07d9ea94d8fb2d1ec19dd206802","observedAt":"2026-10-24T13:19:41.952+00:00","statement":{"source":"osv","id":"GO-2026-6446","aliases":["CVE-2025-24978","GHSA-g8rh-fjm6-h2h9"],"title":"LF Edge eKuiper: Self-XSS in External Service Creation in github.com/lf-edge/ekuiper","description":"LF Edge eKuiper: Self-XSS in External Service Creation in github.com/lf-edge/ekuiper","state":0,"publishedAt":"2026-09-16T16:56:22+00:00","modifiedAt":"2026-09-17T17:30:11.2736311+00:00","affected":[{"ecosystem":"Go","name":"github.com/lf-edge/ekuiper","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"Go","name":"github.com/lf-edge/ekuiper/v2","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2.4.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://github.com/lf-edge/ekuiper/security/advisories/GHSA-g8rh-fjm6-h2h9","https://github.com/lf-edge/ekuiper/releases/tag/v2.4.0"],"sourceUrl":"https://osv.dev/vulnerability/GO-2026-6446","license":"OSV · upstream source license applies","key":"osv:GO-2026-6446","identifiers":["GO-2026-6446","CVE-2025-24978","GHSA-g8rh-fjm6-h2h9"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
