Prior to 3.1.3, the PUT /api/v1/executions/:id endpoint in packages/server/src/routes/executions/index.ts lacks the checkAnyPermission() middleware that protects other execution endpoints. Any authenticated user, regardless of assigned permissions, can modify execution state, data, and metadata of any execution in their workspace, enabling privilege escalation and manipulation of workflow execution results. This issue is fixed in 3.1.3.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":7.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":6.5},"cwes":["CWE-862"],"references":["https://github.com/FlowiseAI/Flowise/commit/96a9b23b5a103b362a0ee1368d04636755be1bed","https://github.com/FlowiseAI/Flowise/pull/6409","https://github.com/FlowiseAI/Flowise/releases/tag/flowise@3.1.3","https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-fm2f-4339-4p2f","https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-fm2f-4339-4p2f"],"products":["flowiseai:flowise"],"source":"nvd","synced_at":"2026-10-24T16:53:34.184483516+00:00"},"epss":{"cve":"CVE-2026-70475","score":0.00458,"percentile":0.39443,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-fm2f-4339-4p2f","url":"https://osv.dev/vulnerability/GHSA-fm2f-4339-4p2f","summary":"Flowise: Missing Authorization on Execution Update Endpoint","modified":"2026-08-04T19:41:02.360Z","packages":[{"ecosystem":"npm","name":"flowise","purl":"pkg:npm/flowise","ranges":["<3.1.3"],"fixed":["3.1.3"]}]}],"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).
