n8n before 1.123.85, 2.43.5, and 2.44.1 Credential Guard Bypass via Execute Sub-workflow

n8n before 1.123.85, 2.43.5, and 2.44.1 contains a credential guard bypass vulnerability that allows editors of shared workflows to use restricted credentials by loading sub-workflows from URLs or local files. Attackers can configure the Execute Sub-workflow node with source url or localFile to serve content that resolves project credentials and returns their decrypted values.

n8n before 2.43.5 and 2.44.1 Authorization Bypass via Crafted Workflow ID in Data Tables

n8n before 2.43.5 and 2.44.x before 2.44.1 accepts a client-supplied workflow ID and caches each workflow's owner project in memory by that ID, so a crafted ID such as __proto__ makes the Data Table project check match every project. An authenticated member who can create and run workflows can list, read, modify, and delete Data Table rows in all projects of the instance.

n8n before 1.123.85, 2.43.5, and 2.44.1 Stored XSS via Webhook Responses Missing Sandbox Policy

n8n before 1.123.85, 2.x before 2.43.5, and 2.44.x before 2.44.1 contains a stored cross-site scripting vulnerability because some webhook response paths, such as error responses and responses without headers, omit the sandbox Content-Security-Policy. Authenticated members who can create and activate workflows can serve HTML that runs on the n8n origin, letting scripts act with the session of users who open the webhook URL.

n8n before 2.41.5 and 2.42.2 Credential Theft via Error-Workflow Context Inheritance

n8n before 2.41.5 and 2.42.x before 2.42.2 passes a failed workflow's full execution context, including the identity of the user who started the run, to the configured error workflow. A project editor can set a colleague's workflow settings.errorWorkflow to an error workflow they own, inherit the colleague's identity when that workflow fails, and resolve the colleague's per-user dynamic credential secrets.

Echo: Decompress permits unbounded gzip expansion in v4

Echo is a Go web framework. From 4.0.0 until 4.16.1, Echo v4's opt-in Decompress middleware exposes a gzip-decoded request stream without limiting its expanded size. A small compressed request can expand into a very large body when a handler reads or binds it, consuming excessive memory or CPU and allowing repeated or concurrent requests to cause denial of service. The middleware is not enabled by default, and limiting only the compressed request size does not bound the decoded size. This issue is fixed in 4.16.1.

Echo: BodyDump captures request and response bodies without size limits in v4

Echo is a Go web framework. From 4.0.0 until 4.16.1, Echo v4's opt-in BodyDump middleware reads complete request bodies into memory before handlers run and retains complete response bodies for the dump callback without capture limits. An unauthenticated client that can reach a route using BodyDump can submit large bodies or influence large responses, causing repeated or concurrent allocations that exhaust process memory. BodyDump is not enabled by default, and external request limits may reduce request-side exposure but do not bound response capture. This issue is fixed in 4.16.1.

opentelemetry-java: Quadratic CPU consumption in W3C tracestate parsing

opentelemetry-java is the Java implementation of the OpenTelemetry API for recording telemetry, and SDK for managing telemetry recorded by the API. Prior to 1.67.0, W3CTraceContextPropagator.extract() uses regex delimiter processing that can exhibit quadratic backtracking while parsing tracestate headers containing long runs of spaces or tabs without a following comma. An unauthenticated attacker whose headers reach extraction can repeatedly block request or event-loop threads and cause excessive CPU consumption, with practical impact bounded by ingress header-size limits, proxy configuration, and threading. This issue is fixed in version 1.6

CVE-2026-118633

A path traversal vulnerability allows a remote unauthenticated attacker to execute arbitrary code as root in Sophos UTM (all versions) after winning a race condition by sustaining repeated attacks for a few minutes when the email proxy is used with scanning enabled. Sophos UTM is end-of-life and the patch must be installed manually.

i18next-http-backend: Query-parameter injection through & and = in lng when loadPath/addPath puts {{lng}} in the query string

i18next-http-backend is a backend layer for i18next that loads translation resources in Node.js, browsers, and Deno. Prior to 4.0.4, interpolateUrl inserts unencoded language and namespace values into loadPath or addPath templates without rejecting ampersand (&), equals (=), or semicolon (;) query separators. When a template places lng or ns in the query string and an attacker controls that value, the attacker can add or override parameters on browser or server-side translation requests, potentially exposing other namespaces or tenants or changing backend behavior through the application's network position and credentials. This vulnerability

Vue I18n: escapeParameter does not prevent XSS through srcdoc in translation messages

Vue I18n is the internationalization plugin for Vue.js. From 11.1.10 until 11.4.14 and from 12.0.0-alpha.4 until 12.0.0-alpha.5, sanitizeTranslatedHtml() escapes markup and event-handler text inside an iframe srcdoc value but leaves the srcdoc attribute active. Browsers decode the character references and parse the value as a same-origin nested HTML document, allowing attacker-controlled parameters or translation content placed in srcdoc to execute script when applications enable escapeParameter and render translations as HTML through v-html. Versions 9.14.5 and 10.0.8 are also affected and are no longer supported, while i18n-t rendering is n

Vue I18n: `escapeParameter` does not escape named values when the same call also passes a list

Vue I18n is the internationalization plugin for Vue.js. From 9.0.0-beta.5 until 11.4.14 and 12.0.0-alpha.5, enabling escapeParameter, called escapeParameterHtml in the Legacy API, does not escape named interpolation values when the same translation call supplies both list and named values because escapeParams() processes only the list branch. Applications that render translations as HTML and pass untrusted named values with a list can insert attacker-controlled markup, including phishing links, forms, and layout changes, and can permit script execution when combined with the srcdoc sanitizer bypass or on releases without the sanitizer.
