n8n has a symlink traversal vulnerability in "Read/Write File" node allows access to restricted files

n8n is a workflow automation platform. Before 1.106.0, a symlink traversal vulnerability was discovered in the Read/Write File node in n8n. While the node attempts to restrict access to sensitive directories and files, it does not properly account for symbolic links (symlinks). An attacker with the ability to create symlinks—such as by using the Execute Command node—could exploit this to bypass the intended directory restrictions and read from or write to otherwise inaccessible paths. Users of n8n.cloud are not impacted. Affected users should update to version 1.106.0 or later.

Directus allows unauthenticated file upload and file modification due to lacking input sanitization

Directus is a real-time API and App dashboard for managing SQL database content. From 10.8.0 to before 11.9.3, a vulnerability exists in the file update mechanism which allows an unauthenticated actor to modify existing files with arbitrary contents (without changes being applied to the files' database-resident metadata) and / or upload new files, with arbitrary content and extensions, which won't show up in the Directus UI. This vulnerability is fixed in 11.9.3.

CVE-2025-50864

An Origin Validation Error in the elysia-cors library thru 1.3.0 allows attackers to bypass Cross-Origin Resource Sharing (CORS) restrictions. The library incorrectly validates the supplied origin by checking if it is a substring of any domain in the site's CORS policy, rather than performing an exact match. For example, a malicious origin like "notexample.com", "example.common.net" is whitelisted when the site's CORS policy specifies "example.com." This vulnerability enables unauthorized access to user data on sites using the elysia-cors library for CORS validation.

Unauthorized third-party images in Astro’s _image endpoint

Astro is a web framework for content-driven websites. In versions of astro before 5.13.2 and 4.16.18, the image optimization endpoint in projects deployed with on-demand rendering allows images from unauthorized third-party domains to be served. On-demand rendered sites built with Astro include an /_image endpoint which returns optimized versions of images. A bug in impacted versions of astro allows an attacker to bypass the third-party domain restrictions by using a protocol-relative URL as the image source, e.g. /_image?href=//example.com/image.png. This vulnerability is fixed in 5.13.2 and 4.16.18.

Command Injection via `format` option in screenshot-desktop

screenshot-desktop allows capturing a screenshot of your local machine. This vulnerability is a command injection issue. When user-controlled input is passed into the format option of the screenshot function, it is interpolated into a shell command without sanitization. This results in arbitrary command execution with the privileges of the calling process. This vulnerability is fixed in 1.15.2.

Mermaid improperly sanitizes of sequence diagram labels leading to XSS

Mermaid is a JavaScript based diagramming and charting tool that uses Markdown-inspired text definitions and a renderer to create and modify complex diagrams. In the default configuration of mermaid 10.9.0-rc.1 to 11.9.0, user supplied input for sequence diagram labels is passed to innerHTML during calculation of element size, causing XSS.

Mermaid does not properly sanitize architecture diagram iconText leading to XSS

Mermaid is a JavaScript based diagramming and charting tool that uses Markdown-inspired text definitions and a renderer to create and modify complex diagrams. In the default configuration of mermaid 11.9.0 and earlier, user supplied input for architecture diagram icons is passed to the d3 html() method, creating a sink for cross site scripting. This vulnerability is fixed in 11.10.0.

Stored XSS in n8n Form Trigger allows Account Takeover via injected iframe and video/source

n8n is a workflow automation platform. From 1.77.0 to before 1.98.2, a stored Cross-Site Scripting (XSS) vulnerability was identified in n8n, specifically in the Form Trigger node's HTML form element. An authenticated attacker can inject malicious HTML via an <iframe> with a srcdoc payload that includes arbitrary JavaScript execution. The attacker can also inject malicious Javascript by using <video> coupled <source> using an onerror event. While using iframe or a combination of video and source tag, this vulnerability allows for Account Takeover (ATO) by exfiltrating n8n-browserId and session cookies from authenticated users who visit a mali

ExpressGateway express-gateway REST Endpoint apps.js cross site scripting

A vulnerability has been found in ExpressGateway express-gateway up to 1.16.10. Affected is an unknown function in the library lib/rest/routes/apps.js of the component REST Endpoint. The manipulation leads to cross site scripting. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

ExpressGateway express-gateway REST Endpoint users.js cross site scripting

The manipulation leads to cross site scripting. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Claude Code's Permissive Default Allowlist Enables Unauthorized File Read and Network Exfiltration in Claude Code

Claude Code is an agentic coding tool. Prior to version 1.0.4, it's possible to bypass the Claude Code confirmation prompts to read a file and then send file contents over the network without user confirmation due to an overly broad allowlist of safe commands. Reliably exploiting this requires the ability to add untrusted content into a Claude Code context window. Users on standard Claude Code auto-update received this fix automatically after release. Current users of Claude Code are unaffected, as versions prior to 1.0.24 are deprecated and have been forced to update.

@backstage/plugin-scaffolder-backend Template Secret Leakage in Logs in Scaffolder When Using `fetch:template`

@backstage/plugin-scaffolder-backend is the backend for the default Backstage software templates. Prior to version 2.1.1, duplicate logging of the input values in the fetch:template action in the Scaffolder meant that some of the secrets were not properly redacted. If ${{ secrets.x }} is not passed through to fetch:template there is no impact. This issue has been resolved in 2.1.1 of the scaffolder-backend plugin. A workaround for this issue involves Template Authors removing the use of ${{ secrets }} being used as an argument to fetch:template.

@astrojs/node's trailing slash handling causes open redirect issue

Astro is a web framework for content-driven websites. Following CVE-2025-54793 there's still an Open Redirect vulnerability in a subset of Astro deployment scenarios prior to version 9.4.1. Astro 5.12.8 addressed CVE-2025-54793 where https://example.com//astro.build/press would redirect to the external origin //astro.build/press. However, with the Node deployment adapter in standalone mode and trailingSlash set to "always" in the Astro configuration, https://example.com//astro.build/press still redirects to //astro.build/press. This affects any user who clicks on a specially crafted link pointing to the affected domain. Since the domain appea

Unsupervised OS command execution leads to remote code execution by unauthenticated network attackers

The Custom MCPs feature is designed to execute OS commands, for instance, using tools like `npx` to spin up local MCP Servers. However, Flowise's inherent authentication and authorization model is minimal and lacks role-based access controls (RBAC). Furthermore, in Flowise versions before 3.0.1 the default installation operates without authentication unless explicitly configured. This combination allows unauthenticated network attackers to execute unsandboxed OS commands.

Unintended dynamic code execution leads to remote code execution by network attackers

User-controlled input flows to an unsafe implementation of a dynamic Function constructor, allowing network attackers to run arbitrary unsandboxed JS code in the context of the host, by sending a simple POST request.

content-security-policy-parser Prototype Pollution Vulnerability May Lead to RCE

content-security-policy-parser parses content security policy directives. A prototype pollution vulnerability exists in versions 0.5.0 and earlier, wherein if a policy name is called __proto__, one can override the Object prototype. This issue has been patched in version 0.6.0. A workaround involves disabling prototype method in NodeJS, neutralizing all possible prototype pollution attacks. Provide either --disable-proto=delete (recommended) or --disable-proto=throw as an argument to node to enable this feature.
