🚨 CVE-2026-77075
n8n before 1.123.69, 2.x before 2.33.4, and 2.34.x before 2.34.1 contain an expression injection vulnerability in resource-locator field link preview rendering. The editor spliced the field's stored value directly into the node type's URL template without checking for expression syntax. An authenticated member can store a malicious value so that when another user opens the affected node in the editor, the injected expression is evaluated as JavaScript in the victim's authenticated session (cross-user script execution).

🚨 CVE-2026-77076
n8n versions before 1.123.69, 2.33.4, and 2.34.1 contain an information disclosure vulnerability in the GraphQL node. When a GraphQL request fails at the connection level, the node re-throws the underlying HTTP client error unchanged instead of wrapping it in n8n's standard error type. That error contains the live request's headers, including a decrypted credential secret, which the execution engine persists verbatim. Any authenticated user able to read the resulting execution can retrieve the decrypted credential secret from the stored run data.

🚨 CVE-2026-77077
n8n versions before 1.123.69, 2.33.4, and 2.34.1 contain a JavaScript task runner VM sandbox escape. The runner's prototype-freezing routine covers globalThis functions but not internal module constructors such as EventEmitter, allowing an authenticated user with Code node access to exploit prototype pollution to execute arbitrary commands within the runner container. Because the polluted prototype is a process-wide object, the corruption persists across other tenants' Code node executions on the same shared runner. On v1.x instances without task runners enabled, Code node JavaScript runs directly in the main n8n process, where the impact could be higher.

n8n before 1.123.69, 2.x before 2.33.4, and 2.x before 2.34.1 contain an allowed-domains bypass in the GraphQL node. When the node's Authentication parameter is set to expression mode, every authentication-gated credential selector is treated as active; if two credentials of different types are attached, the node enforces the allowed-domains policy of only the first credential while still attaching material from both. An authenticated user with workflow-authoring rights can thereby send a domain-restricted credential to an attacker-controlled endpoint, exfiltrating it with the leaked credential's permissions.

🚨 CVE-2026-77083
n8n is a workflow automation platform. In versions prior to 1.123.69, 2.33.4, and 2.34.1, the JavaScript Code node's VM sandbox did not freeze the sandbox's Function.prototype, allowing an authenticated user with the ability to create and execute workflows to pollute it from within a Code node execution and recover a reference to the host's globalThis, resulting in a sandbox escape. The full exploit chain additionally depends on specific modules being available as allowlisted imports in the deployment's configuration. The issue is fixed in versions 1.123.69, 2.33.4, and 2.34.1.

🚨 CVE-2026-68921
DiceBear is an avatar library for designers and developers. Prior to 9.4.3, @dicebear/core interpolates the rotate option into an SVG transform attribute without XML escaping in addRotate in packages/@dicebear/core/src/utils/svg.ts, while @dicebear/initials similarly emits fontSize and fontWeight without escaping in packages/@dicebear/initials/src/index.ts. Runtime callers can pass strings despite the numeric TypeScript types, break out of the attributes, and inject arbitrary SVG markup. Script can execute in the page origin when the generated avatar is inserted inline or served as image/svg+xml and opened directly, although exploitation requires an application to pass untrusted values into these normally developer-controlled options. This issue is fixed in @dicebear/core and @dicebear/initials version 9.4.3.
