| CVE-2026-59257 | 1 N8n | 1 N8n | 2026-10-29 | N/A | 8.8 HIGH |
| n8n before 1.123.61, 2.x before 2.27.4, and 2.28.x before 2.28.1 contains a SQL injection vulnerability in the legacy MySQL v1 node's executeQuery operation. The operation substitutes evaluated {{ ... }} expression values directly into the raw SQL string without parameterization. When a workflow uses this operation with expression-sourced values and is connected to an externally-reachable trigger (such as a Webhook node), attacker-controlled input reaching those expressions results in SQL injection, allowing execution of arbitrary SQL with the configured MySQL credentials' privileges. The MySQL v2 node, which uses parameterized queries, is not affected. | |||||
| CVE-2026-58661 | 1 N8n | 1 N8n | 2026-10-29 | N/A | 4.3 MEDIUM |
| n8n before 2.28.0 (and before 1.123.58 on the 1.x branch) contains a disk space exhaustion vulnerability in the data-table file upload endpoint. The per-request quota check does not account for files already written to the shared temporary directory, allowing an authenticated user to repeatedly upload files that accumulate on disk until the periodic cleanup runs, potentially exhausting available disk space on the host. | |||||
| CVE-2026-56778 | 1 N8n | 1 N8n | 2026-10-29 | N/A | 6.4 MEDIUM |
| n8n before 2.25.7 and 2.26.x before 2.26.2 contains an authorization bypass in the Public API execution retry endpoint, which authorizes access using the workflow:read scope instead of workflow:execute. An authenticated user with read-only access to a shared workflow can use the Public API to retry executions of that workflow, bypassing the intended permission boundary between read and execute access. This affects instances where workflows are shared with other users or across projects. | |||||
| CVE-2026-56777 | 1 N8n | 1 N8n | 2026-10-29 | N/A | 5.0 MEDIUM |
| n8n before 2.25.7 and 2.26.x before 2.26.2 contains an abstract syntax tree (AST) security validator bypass in the Python Code node. An authenticated user with permission to create or modify workflows containing a Python Code node can bypass the validator and access the task executor module namespace. The issue only affects self-hosted instances where the Python Task Runner is enabled; where N8N_BLOCK_RUNNER_ENV_ACCESS is configured to allow it, this can disclose environment variables accessible to the task runner process. | |||||
| CVE-2026-56776 | 1 N8n | 1 N8n | 2026-10-29 | N/A | 7.4 HIGH |
| n8n before 1.123.55, 2.25.7, and 2.26.2 contains an authorization bypass in the POST /workflows/{workflowId}/test-runs/new endpoint, which authorizes access using the workflow:read scope instead of workflow:execute. An authenticated user with read-only access to a workflow can trigger a real evaluation test run, causing the workflow to execute via the internal workflow runner and resulting in unintended outbound API calls, data mutations, or other side effects in connected downstream systems. The issue primarily affects instances using the Evaluations feature where RBAC project roles grant workflow:read without workflow:execute. | |||||
| CVE-2026-56775 | 1 N8n | 1 N8n | 2026-10-29 | N/A | 5.4 MEDIUM |
| n8n before 1.123.55, 2.25.7, and 2.26.2 contains an authorization vulnerability in three mutating evaluation test-run endpoints that authorize state-changing actions using the workflow:read scope instead of the action-appropriate workflow:execute scope. On instances using Advanced Permissions (Enterprise/Cloud) with projects and viewer roles, an authenticated user with the project:viewer role can start new evaluation test runs, cancel in-flight runs, and delete run records for workflows they only have read access to. | |||||
| CVE-2026-56359 | 1 N8n | 1 N8n | 2026-10-29 | N/A | 5.4 MEDIUM |
| n8n before 2.8.0 contains a cross-site scripting vulnerability in the credential management flow where authenticated users can inject malicious JavaScript URLs into OAuth2 credential Authorization URL fields. Attackers can craft malicious credentials and trick victims into clicking the OAuth authorization button, executing arbitrary scripts in their browser session with the victim's privileges. | |||||
| CVE-2026-56358 | 1 N8n | 1 N8n | 2026-10-29 | N/A | 5.4 MEDIUM |
| n8n before 1.123.25 (1.x) and before 2.11.2 (2.x), with the fix also included in 2.12.0, contains a stored cross-site scripting vulnerability in the Form Trigger node's CSS sanitization that allows authenticated users to inject malicious scripts. Attackers with workflow creation permissions can inject XSS payloads that execute persistently for all form visitors, enabling form hijacking and phishing attacks. | |||||
| CVE-2026-56356 | 1 N8n | 1 N8n | 2026-10-29 | N/A | 5.4 MEDIUM |
| n8n contains a stored cross-site scripting vulnerability in the Chat Trigger node's Custom CSS field due to a misconfiguration of the sanitize-html library. Affected releases are those before 1.123.27, the 2.0.0 through 2.13.2 line, and 2.14.0 (fixed in 1.123.27, 2.13.3, and 2.14.1). An authenticated user with permission to create or modify workflows can inject JavaScript that bypasses sanitization, resulting in stored XSS against any user who visits the public chat page. | |||||
| CVE-2026-56354 | 1 N8n | 1 N8n | 2026-10-29 | N/A | 4.1 MEDIUM |
| n8n before 1.123.24, 2.10.4, and 2.12.0 (across its 1.x and 2.x branches) contains cross-site scripting and open redirect vulnerabilities in the Form Node due to unsanitized HTML description fields and overly permissive iframe sandbox policies. Authenticated users with workflow creation permissions can inject malicious scripts or redirect parameters to perform stored XSS attacks or phishing redirects against end users. | |||||
| CVE-2026-54303 | 1 N8n | 1 N8n | 2026-10-26 | N/A | 5.4 MEDIUM |
| n8n is an open source workflow automation platform. Prior to 2.24.0, an endpoint in the Meta and Microsoft Teams trigger nodes reflects a query parameter into the HTTP response without sanitization or Content-Security-Policy headers, enabling reflected XSS in the n8n origin when a logged-in user visits a crafted URL. This vulnerability is fixed in 2.24.0. | |||||
| CVE-2026-44789 | 1 N8n | 1 N8n | 2026-10-26 | N/A | 9.9 CRITICAL |
| n8n is an open source workflow automation platform. Prior to 1.123.43, 2.22.1, and 2.20.7, an authenticated user with permission to create or modify workflows could achieve global prototype pollution via an unvalidated pagination parameter in the HTTP Request node. Combined with other techniques this could lead to RCE on the instance. This vulnerability is fixed in 1.123.43, 2.22.1, and 2.20.7. | |||||
| CVE-2026-54301 | 1 N8n | 1 N8n | 2026-10-26 | N/A | 5.4 MEDIUM |
| n8n is an open source workflow automation platform. Prior to 1.123.55, 2.25.7, and 2.26.2, an authenticated user with workflow edit access could configure a Respond to Webhook node to serve binary content with an attacker-controlled Content-Type. The binary response path bypassed the central Content-Security-Policy sandbox header, allowing a public webhook to execute JavaScript in the n8n origin when visited by an authenticated user, with access to that user's session. This vulnerability is fixed in 1.123.55, 2.25.7, and 2.26.2. | |||||
| CVE-2026-44792 | 1 N8n | 1 N8n | 2026-10-26 | N/A | 9.0 CRITICAL |
| n8n is an open source workflow automation platform. Prior to 1.123.43, 2.22.1, and 2.20.7, an attacker with write access to the git repository connected to an n8n Source Control configuration could commit a malicious Data Table JSON file containing a crafted column name. When an administrator performed a Source Control Pull, n8n imported the file and could lead to SQL injection on the internal PostgreSQL instance. Exploitation requires the n8n instance uses PostgreSQL as its database backend, the Source Control feature is enabled and connected to a repository the attacker can write to, and an administrator triggers a Source Control Pull. This vulnerability is fixed in 1.123.43, 2.22.1, and 2.20.7. | |||||
| CVE-2026-44790 | 1 N8n | 1 N8n | 2026-10-26 | N/A | 8.8 HIGH |
| n8n is an open source workflow automation platform. Prior to 1.123.43, 2.22.1, and 2.20.7, an authenticated user with permission to create or modify workflows could inject CLI flags on the Git node's Push operation allowing an attacker to read arbitrary files from the n8n server potentially leading to full compromise. This vulnerability is fixed in 1.123.43, 2.22.1, and 2.20.7. | |||||
| CVE-2026-54311 | 1 N8n | 1 N8n | 2026-10-26 | N/A | 7.7 HIGH |
| n8n is an open source workflow automation platform. Prior to 2.25.7 and 2.26.2, an authenticated user with permission to create or modify workflows could pollute the sandbox used by the Merge node's SQL Query mode. Because the sandbox context was cached and reused across all workflow executions on the instance, prototype mutations introduced by one user's workflow persist into subsequent Merge SQL executions belonging to other users or projects. This allowed a low-privileged attacker to intercept workflow data processed by other users on the same instance. This issue only affects multi-user n8n instances where more than one user has permission to create and execute workflows containing the Merge node in SQL Query mode. This vulnerability is fixed in 2.25.7 and 2.26.2. | |||||
| CVE-2026-54309 | 1 N8n | 1 N8n | 2026-10-26 | N/A | 10.0 CRITICAL |
| n8n is an open source workflow automation platform. Prior to 2.25.7 and 2.26.2, when @n8n/mcp-browser is run in HTTP transport mode, the MCP endpoint accepts session initialization and tool invocation requests without any authentication. Any network-reachable client, or any website visited by the user, can establish an MCP session and invoke browser-control tools. Where the n8n AI Browser Bridge extension is installed and a browser connection is active, an unauthenticated caller can access browser-control capabilities including navigation, JavaScript evaluation, and cookie and storage access against the user's real browser profile. This issue only affects instances where @n8n/mcp-browser is run with the HTTP transport (--transport http). This vulnerability is fixed in 2.25.7 and 2.26.2. | |||||
| CVE-2026-45732 | 1 N8n | 1 N8n | 2026-10-26 | N/A | 8.1 HIGH |
| n8n is an open source workflow automation platform. Prior to 1.123.43, 2.22.1, and 2.20.7, the OAuth1 and OAuth2 credential reconnect endpoints authorized access using credential:read rather than credential:update. An authenticated user with read-only access to a shared credential could initiate an OAuth reconnect flow and overwrite the stored token material for that credential with tokens bound to an external account they control. Workflows relying on the affected credential would subsequently execute under the attacker's OAuth identity, enabling data exfiltration to attacker-controlled external services and persistent takeover of shared integrations. This vulnerability is fixed in 1.123.43, 2.22.1, and 2.20.7. | |||||
| CVE-2026-49465 | 1 N8n | 1 N8n | 2026-10-26 | N/A | 7.7 HIGH |
| n8n is an open source workflow automation platform. Prior to 1.123.48, 2.21.8, and 2.22.4, an authenticated user with permission to create or modify workflows could supply a local filesystem path as the source repository in the Git node's Clone operation, or as the target repository in the Push operation, bypassing the N8N_RESTRICT_FILE_ACCESS_TO file sandbox. This allowed the contents of any local git repository accessible to the n8n process to be cloned into an allowed path and read, circumventing the access restrictions that correctly blocked direct file reads to the same paths. This vulnerability is fixed in 1.123.48, 2.21.8, and 2.22.4. | |||||
| CVE-2026-44791 | 1 N8n | 1 N8n | 2026-10-26 | N/A | 9.9 CRITICAL |
| n8n is an open source workflow automation platform. Prior to 1.123.43, 2.22.1, and 2.20.7, an authenticated user with permission to create or modify workflows could bypass the patch for CVE-2026-42232 in the XML node. When combined with other nodes, this could lead to RCE on the n8n host. This vulnerability is fixed in 1.123.43, 2.22.1, and 2.20.7. | |||||
