{"id":"CVE-2026-41278","aliases":["GHSA-w47f-j8rh-wx87"],"url":"https://o3.security/vulnerability/CVE-2026-41278","summary":"Flowise: Public chatflow endpoints return unsanitized flowData including plaintext API keys, passwords, and credential IDs","details":"Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, the GET /api/v1/public-chatflows/:id endpoint returns the full chatflow object without sanitization for public chatflows. Docker validation revealed this is worse than initially assessed: the sanitizeFlowDataForPublicEndpoint function does NOT exist in the released v3.0.13 Docker image. Both public-chatflows AND public-chatbotConfig return completely raw flowData including credential IDs, plaintext API keys, and password-type fields. This vulnerability is fixed in 3.1.0.","published":"2026-04-23T19:52:20.973Z","modified":"2026-08-12T03:51:17.490736115Z","cvss":null,"epss":{"score":0.00421,"percentile":0.34703,"asOf":"2026-08-10"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"flowise","fixedVersion":"3.1.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41278.json"},{"type":"ADVISORY","url":"https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-w47f-j8rh-wx87"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41278"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:17.490736115Z"}}
