Top Risky CVEs
| CVE | Summary | Severity | CVSS | EPSS | Priority | Signals |
|---|---|---|---|---|---|---|
| CVE-2025-59528 | Flowise version 3.0.5 contains a remote code execution vulnerability in the CustomMCP node. The mcpServerConfig parameter is parsed unsafely, allowing attackers to inject arbitrary system commands through the MCP server configuration that are executed when Flowise spawns the MCP server process. | CRITICAL | 10.0 | 83.0% | 168 |
PoC
|
| CVE-2026-30821 | Unrestricted file upload in Flowise LLM workflow builder before 3.0.13 via /api/v1/attachments endpoint allows unauthenticated attackers to upload and execute malicious files. PoC available. | CRITICAL | 9.8 | 0.1% | 69 |
PoC
|
| CVE-2026-30824 | Missing authentication on NVD data endpoint in Flowise before 3.0.13 allows unauthenticated access to internal vulnerability data. PoC available. | CRITICAL | 9.8 | 0.0% | 69 |

| CVE-2026-70470 | Remote code execution in Flowise before 3.1.3 arises because its Pyodide Python-code validator (validatePythonCodeForDataFrame) can be defeated with Unicode homoglyph identifiers, letting an attacker run arbitrary Python that escapes the Pyodide sandbox and executes OS commands on the Flowise host with the process's privileges. The affected CSV Agent and Airtable Agent nodes gate LLM-generated (and config-supplied) Python through an ASCII word-boundary regex blacklist, which Python's NFKC identifier normalization silently rewrites back into the forbidden dunders. There is no public exploit identified at time of analysis and it is not in CISA KEV, but the GitHub advisory documents a complete, reproducible bypass technique, so weaponization is straightforward; the vendor rates it 9.5 (CVSS 4.0). | CRITICAL | 9.5 | 0.5% | 68 |

|
| CVE-2026-69264 | Remote code execution in FlowiseAI Flowise before 3.1.3 lets an attacker execute arbitrary OS commands as the Flowise process by abusing the CSVAgent node, which interpolates an attacker-controlled base64 segment of the csvFile data URI directly into a Python template run by Pyodide. Because Pyodide's default js bridge exposes globalThis (including eval and dynamic import on Node.js), the injected code can break out of the Python string, call js.eval, import fs and child_process, and run host commands; the surrounding validators are never applied to this bootstrap template. A low-privileged workspace user plants the malicious node, after which any unauthenticated request to the public POST /api/v1/prediction/:id endpoint triggers the RCE. No public exploit is identified at time of analysis (no KEV, no POC signal in the provided data), but the fix is confirmed in version 3.1.3. | CRITICAL | 9.4 | 0.6% | 68 |
PoC
|
| CVE-2026-73483 | Remote command execution in Flowise <= 3.1.2 lets an authenticated user break out of the vm2/@flowiseai/nodevm JavaScript sandbox by abusing the /api/v1/node-custom-function endpoint. By passing attacker-controlled executablePath and args into puppeteer.launch(), the code reaches child_process.spawn() outside the sandbox, yielding arbitrary OS command execution as the Flowise process user (root in the official Docker image) and host file disclosure via Chromium's file:// handling. No public exploit is identified at time of analysis, but a vendor security advisory (GHSA-9gvv-qjj3-2p6g) and VulnCheck confirm the flaw; the CVSS 4.0 base score is 9.4. | CRITICAL | 9.4 | 0.4% | 67 |
PoC
|
| CVE-2026-46442 | Authenticated remote code execution in FlowiseAI Flowise prior to 3.1.2 allows any user with a valid session or API key to submit arbitrary JavaScript via POST /api/v1/node-custom-function, which executes inside a NodeVM sandbox that can be escaped to reach the host process and spawn child processes. CVSS 4.0 scores this 9.4 Critical, and publicly available exploit details exist via the GHSA advisory, though no public exploit identified at time of analysis in CISA KEV. The flaw stems from missing route-level authorization combined with a sandbox that Flowise itself documents as a security boundary but which fails to contain malicious payloads. | CRITICAL | 9.4 | 0.3% | 67 |

|
| CVE-2026-73601 | Remote code execution in Flowise before 3.1.3 lets authenticated users abuse the Custom MCP node - when CUSTOM_MCP_PROTOCOL is set to stdio - to run arbitrary OS commands on the host. By manipulating environment variables (PYTHONWARNINGS, BROWSER) passed to python3 or leveraging node with the root working directory, an attacker bypasses input validation and achieves command execution as the Flowise service account. Reported by VulnCheck with a CVSS 4.0 score of 9.0; no public exploit is identified at time of analysis, though the technique is documented in detail in the vendor advisory. | CRITICAL | 9.0 | 0.6% | 66 |
PoC
|
| CVE-2026-73602 | Remote code execution in Flowise before 3.1.3 lets authenticated users escape the vm2 JavaScript sandbox and run arbitrary code on the host. By abusing a moment.js locale-validation weakness, an attacker supplies a forged String object whose match function defeats the path-traversal check, causing Flowise to load and execute an attacker-planted JavaScript file from the document store outside the sandbox. Reported by VulnCheck and fixed by the vendor; no public exploit or CISA KEV listing was identified at time of analysis, though the CVSS 4.0 base score of 9.0 reflects full compromise of confidentiality, integrity, and availability. | CRITICAL | 9.0 | 0.4% | 65 |

| CVE-2026-73487 | Remote code execution and SSRF in FlowiseAI Flowise before 3.1.3 stems from a bypassable regex-based Python code validator in the CSV and Airtable Agent nodes, letting attackers smuggle malicious pandas calls through the unauthenticated prediction API via prompt injection. Because the validator blocklists rather than sandboxes, unblocked functions such as pd.read_json() can be abused to exfiltrate local datasets, reach internal services (SSRF), or execute arbitrary code. No public exploit identified at time of analysis, and it is not listed in CISA KEV; the reporting vendor VulnCheck and a GitHub Security Advisory (GHSA-w7x8-q2gp-5cgg) document the issue. | CRITICAL | 9.0 | 0.4% | 65 |

|
| CVE-2026-73486 | Authenticated arbitrary Python code execution in FlowiseAI Flowise before 3.1.3 arises from the CSV Agent node's customReadCSV parameter, whose regex-based validator can be defeated with obfuscation to run attacker-supplied code inside an unsandboxed pyodide runtime with full host access. Any user able to build or edit a chatflow can escalate from application-level access to code execution on the server. No public exploit has been identified at time of analysis, and the issue is not listed in CISA KEV; a vendor patch exists in version 3.1.3. | CRITICAL | 9.0 | 0.3% | 65 |

|
| CVE-2026-73485 | Remote code execution in Flowise before 3.1.3 lets attackers run arbitrary Python on the host by abusing the Airtable Agent node. Crafted chatflow prompts carry obfuscated Python that slips past the pythonCodeValidator blocklist and executes inside an unsandboxed pyodide runtime with full access to the underlying OS. Reported by VulnCheck with a published GHSA advisory; no public exploit code is identified at time of analysis, and it is not listed in CISA KEV. | CRITICAL | 9.0 | 0.3% | 65 |

| CVE-2026-30820 | Privilege escalation in Flowise versions prior to 3.0.13 allows authenticated users to bypass API authorization by spoofing an internal request header, granting access to sensitive administrative functions including API key and credential management. Public exploit code exists for this vulnerability, and an attacker with valid tenant credentials can escalate to administrative privileges without additional authentication. No patch is currently available for affected deployments. | HIGH | 8.8 | 0.1% | 64 |

| CVE-2026-30823 | Flowise versions up to 3.0.13 is affected by authorization bypass through user-controlled key (CVSS 8.8). | HIGH | 8.8 | 0.0% | 64 |

|
| CVE-2026-71962 | Unauthenticated file exfiltration in Flowise 2.2.4-3.1.4 is possible because the POST /api/v1/openai-assistants-file/download endpoint was incorrectly added to the application's global authentication whitelist, causing all session and API key verification to be skipped unconditionally. Any remote, unauthenticated attacker who can supply valid chatflowId, chatId, and fileName identifiers can retrieve private files from any chatflow on the instance, including those belonging to other workspaces or organizations in a multi-tenant deployment. A public proof-of-concept exploit is available via GitHub, and no KEV listing has been confirmed at time of analysis. | HIGH | 8.7 | 0.4% | 64 |
