CVE	Summary	Severity	CVSS	EPSS	Priority
CVE-2026-71539	Remote code execution in n8n workflow automation platform (all versions prior to 1.123.64, 2.29.8, and 2.30.1) stems from a TOCTOU race condition in the Git node's clone operation, allowing any low-privileged authenticated user to achieve arbitrary JavaScript execution on the server. The attacker wins a race between path validation and the actual clone, replacing a legitimate directory with a symlink to plant a crafted repository in n8n's community node directory - which the platform loads and executes as trusted JavaScript on the next restart. Both self-hosted and cloud-hosted n8n instances are affected wherever authenticated users can create and run workflows containing the Git node; no public exploit or CISA KEV listing has been identified at time of analysis.	HIGH	8.9	0.2%	44
CVE-2026-77068	Remote code execution in n8n workflow automation platform (versions before 2.33.4 and 2.34.x before 2.34.1) arises from a path traversal flaw in the @n8n/workflow-sdk MCP node-schema loader. An authenticated user holding global:member privileges can supply a crafted node type string containing path-traversal sequences, causing the loader to resolve and execute an arbitrary file on the server filesystem as a Node.js module within the n8n main process. No public exploit has been identified at time of analysis and the vulnerability is not in the CISA KEV catalog, but the low privilege requirement and straightforward exploitability make this a high-priority patch for all self-hosted n8n deployments.	HIGH	8.7	0.5%	44
CVE-2026-85169	Prototype chain sandbox escape in n8n's $fromAI expression handler allows any user holding workflow-build privilege to achieve remote code execution within the main n8n server process. The $fromAI handler failed to restrict placeholder key lookup to own properties and permitted reserved prototype keys; when the input value is a primitive, the handler returns a live reference to the host-prototype chain, enabling traversal to Function.prototype.constructor and compilation of arbitrary JavaScript outside the expression sandbox. All n8n deployments running versions below 1.123.73 (v1 track), 2.35.4, or 2.36.2 (v2 track) are affected. No public exploit code or CISA KEV listing has been identified at time of analysis, but the technique (prototype chain walk to Function constructor) is well-understood and reliable once sandbox access is obtained.	HIGH	8.7	0.4%	44
CVE-2026-77080	Arbitrary file read and write in n8n's Snowflake node allows an authenticated low-privileged user to exfiltrate or overwrite files on the n8n host by injecting Snowflake client-side commands (PUT/GET) into the Execute Query input field, bypassing n8n's own file-access restrictions. Affected versions span n8n before 1.123.69, all 2.x builds before 2.33.4, and 2.34.x before 2.34.1, as confirmed by vendor advisory GHSA-r4j2-j3wm-q689. No public exploit code has been identified at time of analysis, but the CVSS 4.0 score of 8.7 and the low barrier to exploitation - requiring only n8n credentials plus access to a Snowflake connection - make this a high-priority remediation.	HIGH	8.7	0.2%	44
CVE-2026-77075	Expression injection in n8n's workflow editor allows an authenticated member to store a malicious payload in a resource-locator field that executes as JavaScript in any other user's browser session when they open the affected node. The root cause is that the editor splices the field's stored value directly into the node type's URL template without sanitizing expression syntax, enabling cross-user script execution within authenticated sessions. No public exploit or CISA KEV listing has been identified at time of analysis, but the CVSS 4.0 score of 8.4 reflects high confidentiality and integrity impact on the vulnerable system.	HIGH	8.4	0.3%	42
CVE-2026-77072	Stored XSS in n8n's Form node completion page allows a low-privileged authenticated workspace member to bypass the origin's Content-Security-Policy and deliver arbitrary scripts to public form submitters. The flaw stems from a conditional CSP application gap: sandboxing was only enforced when `respondWith` was not set to 'redirect', yet `responseText` was rendered as raw HTML regardless of that setting. Scripts injected this way execute same-origin with the victim's n8n session, enabling session token theft, credential harvesting, or unauthorized actions. No public exploit code or CISA KEV listing has been identified at time of analysis.	HIGH	8.4	0.2%	42
CVE-2026-85168	Remote code execution in n8n's Git node allows an authenticated workflow user to execute arbitrary OS commands as the n8n process user by pointing the node at a repository containing malicious git configuration. The vulnerability arises from an incomplete sanitization list that omitted the content-filter and merge-driver git configuration key families, allowing those keys to survive into git operations and trigger arbitrary command execution during routine Add, Commit, Checkout, or Pull operations. Patched versions 1.123.73, 2.35.4, and 2.36.2 are confirmed available; no public exploit or CISA KEV listing has been identified at time of analysis.	HIGH	7.7	0.4%	39
CVE-2026-77084	Code execution in n8n's Git node (all 1.x releases before 1.123.69, all 2.x releases before 2.33.4 and 2.34.1) allows an authenticated attacker who can also plant files on the n8n host to run arbitrary OS commands as the n8n process user. The Git node passes repository-local git configuration values directly to execution without neutralization, satisfying CWE-78 (OS Command Injection); triggering any Git node operation against a repository whose config has been poisoned fires the injected command automatically. No public exploit has been identified at time of analysis, but the high impact triad (VC:H/VI:H/VA:H) and confirmed patch availability make immediate upgrading the correct response.	HIGH	7.7	0.3%	39
CVE-2026-77079	Privilege escalation in n8n's custom project role management allows users holding only the narrow `role:manageProject` global scope to seize full administrative control over arbitrary projects across the entire instance. The root cause is a missing project-level authorization check in the role deletion-with-reassignment code path: the API validates only that the reassignment target role exists and is project-scoped, never verifying that the requesting user has any rights over the affected projects or their members. No public exploit has been identified and no CISA KEV listing exists at time of analysis; patches are confirmed available in versions 2.33.4 and 2.34.1.	HIGH	7.4	0.2%	37
CVE-2026-77077	Prototype pollution in n8n's JavaScript task runner sandbox allows an authenticated user with Code node access to escape VM isolation and execute arbitrary OS commands within the runner container. Affected versions span the v1.x branch before 1.123.69 and the v2.x branch before 2.33.4 and 2.34.1. The corruption is process-wide, meaning a single malicious execution can poison the prototype chain for all subsequent tenant Code node runs on the same shared runner; on v1.x instances without task runner isolation, the attack surface escalates to the main n8n process itself. No public exploit has been identified at time of analysis and CISA KEV does not list this CVE.	HIGH	7.2	0.4%	36
CVE-2026-85165	Expression sandbox bypass in n8n before 2.36.2 allows authenticated workflow editors to escape the sandboxed evaluation environment by placing free identifiers in spread, computed-key, switch-case, or class-extension positions, which resolve against Node.js process globals instead of the restricted sandbox scope. Exploiting this flaw enables mutation of host objects - including prototype chains or environment-level state - with those changes persisting process-wide until the n8n service is restarted, affecting all concurrent workflows and users on the same instance. No public exploit or CISA KEV listing has been identified at time of analysis; patch version 2.36.2 is confirmed via the GitHub Security Advisory.	HIGH	7.2	0.3%	36
CVE-2026-85166	Credential exfiltration in n8n's workflow execution engine allows a low-privileged authenticated user to reference another user's credentials inside an inline sub-workflow node (such as the Workflow Tool node) without any ownership validation. Affected versions are n8n before 2.35.4 and 2.36.x before 2.36.2. When a privileged execution context later runs the poisoned workflow and resolves the referenced secret, the sub-workflow can forward the plaintext credential to an attacker-controlled endpoint. No public exploit code has been identified at time of analysis, but the VulnCheck advisory corroborates the GitHub Security Advisory GHSA-4r56-g65c-fm83.	HIGH	7.2	0.2%	36
CVE-2026-85171	Credential exposure in n8n's Strapi, SeaTable, and Mailcheck integration nodes causes plaintext API secrets to persist in execution error logs, readable by any authenticated user via the REST API. The three affected nodes pass decrypted credentials to external authentication endpoints through a legacy HTTP helper that lacks error-handling wrappers; when those calls fail, the raw secret is written into execution error records rather than being suppressed or redacted. This bypasses n8n's credential API blank-value redaction, effectively leaking third-party service credentials to any n8n user who can inspect execution results. No public exploit or CISA KEV listing exists at time of analysis; patches are available in versions 1.123.73, 2.35.4, and 2.36.2.	HIGH	7.1	0.4%	36
CVE-2026-77076	Decrypted credential secrets are exposed in execution logs in n8n workflow automation software across versions before 1.123.69, 2.33.4, and 2.34.1. The GraphQL node fails to wrap connection-level HTTP client errors in n8n's standard error type, propagating raw error objects - which carry decrypted credential headers - directly into the persistent execution record. Any authenticated user with read access to workflow execution history can recover those plaintext secrets. No public exploit has been identified at time of analysis, and the vulnerability is not listed in CISA KEV, but the low-privilege access requirement and direct credential exposure make this a high-priority remediation target for shared or multi-tenant deployments.	HIGH	7.1	0.3%	36
CVE-2026-77071	PostgREST filter injection in n8n's Supabase integration node exposes any connected Supabase database to full-table disclosure, deletion, or modification across versions before 1.123.69, 2.33.4, and 2.34.1. The Row Get Many, Delete, and Update operations concatenate expression-bindable values into filter queries without sanitization, allowing an attacker who can supply input to a workflow to widen a scoped filter into an unfiltered full-table operation. No public exploit identified at time of analysis, but the CVSS 4.0 subsequent-system impact is rated high across confidentiality, integrity, and availability, reflecting the catastrophic downstream database risk.
