{"cve":"CVE-2026-69256","nvd":{"published":"2026-08-04T17:17:00.707","modified":"2026-10-24T16:10:00.153","status":"Analyzed","description":"Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, the CSVAgent node allowed users to provide Python code that is executed through pyodide; although a denylist blocked dangerous Python constructs, pandas.read_pickle() could deserialize a pickled payload and achieve code execution without matching the denied words. The affected file is flowise-components/nodes/agents/CSVAgent/CSVAgent.ts, where user-supplied customReadCSVFunc is evaluated as pd.${customReadCSVFunc}. An authenticated user who can create or modify a chatflow can add a CSV Agent, place a malicious read_pickle payload in the Additional Parameters, save the chatflow, and trigger /api/v1/prediction/<UUID> to execute commands. This issue is fixed in version 3.1.3.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":9.4},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-94"],"references":["https://github.com/FlowiseAI/Flowise/commit/c79fe56a6c249850e96bce9b4859f7a0083e4507","https://github.com/FlowiseAI/Flowise/pull/6257","https://github.com/FlowiseAI/Flowise/releases/tag/flowise@3.1.3","https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-x6vm-w76m-8j7g","https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-x6vm-w76m-8j7g"],"products":["flowiseai:flowise"],"source":"nvd","synced_at":"2026-10-24T16:53:34.184483516+00:00"},"epss":{"cve":"CVE-2026-69256","score":0.0101,"percentile":0.62896,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-x6vm-w76m-8j7g","url":"https://osv.dev/vulnerability/GHSA-x6vm-w76m-8j7g","summary":"Flowise: Remote Code Execution Vulnerability in CSVAgent","modified":"2026-08-04T18:00:18.084804722Z","packages":[{"ecosystem":"npm","name":"flowise-components","purl":"pkg:npm/flowise-components","ranges":["<3.1.3"],"fixed":["3.1.3"]},{"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).
