Source description
As published by the source; long descriptions are shortened.
Summary eKuiper /config/uploads API supports accessing remote web URLs and saving files in the local upload directory, but there are no security restrictions, resulting in arbitrary file writing through ../. If run with root privileges, RCE can be achieved by writing crontab files or ssh keys. Details - The fc.Name parameter do not safely filtered. PoC Impact Tested and verified only on 1.14.3 and 1.14.1, theoretically all versions using this code could be affected. 1. SSRF 2. Path-Travel 3. May leads to RCE The reporters is m0d9 from Tencent YunDing Lab.

# Patch Next advisory brief: GHSA-gj54-gwj9-x2c6 Advisory: eKuiper /config/uploads API arbitrary file writing may lead to RCE IDs: GHSA-gj54-gwj9-x2c6 Record: https://patchnext.com/advisories/ghsa-gj54-gwj9-x2c6 (revision 1, source checked 26 Oct 2026, 15:09 UTC) Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected. Severity: High (CVSS 7.3) Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV. Vendor response: Partial vendor fix; fixed versions by package: github.com/lf-edge/ekuiper/v2 2.2.0. A vendor fix does not mean a deployment is fixed. ## Affected components - Go github.com/lf-edge/ekuiper/v2: affected < 2.2.0; fixed in 2.2.0 - Go github.com/lf-edge/ekuiper: affected <= 1.14.7 ## Suggested inspection (read-only) - Go github.com/lf-edge/ekuiper/v2: check the installed version with your package manager. - Go github.com/lf-edge/ekuiper: check the installed version with your package manager. ## Supported action No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything. ## Required regression checks - Run the test suite and a production build. - Exercise the features that depend on github.com/lf-edge/ekuiper/v2, github.com/lf-edge/ekuiper. - Repeat the inspection and confirm that only fixed versions remain installed. ## Rollback considerations - Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward. ## Unresolved questions - Which deployments run an affected version? - Exploitation status can change. Check again before lowering the priority. - Mark the work resolved only after the fixed version is verified in production. ## Sources - Verified: https://github.com/advisories/GHSA-gj54-gwj9-x2c6 (GitHub-reviewed advisory GHSA-gj54-gwj9-x2c6 lists affected ranges: Go github.com/lf-edge/ekuiper/v2 >=0 =0 <=1.14.7) Commands are suggestions: review each one before running it.
