GHSA-2X35-3FW4-9JR4 n8n: Send Email Node Arbitrary File Read and SSRF via Nodemailer Content-Object Type Confusion

Impact The n8n Send Email node did not enforce that its message fields were strings, so a crafted untrusted non-string value from a workflow expression could be treated by the underlying mail library as a file path or URL. This could allow disclosure of local files on the n8n host. Exploitation...

Server-side Request Forgery (SSRF)

Overview @n8n/n8n-nodes-langchain is a Affected versions of this package are vulnerable to Server-side Request Forgery SSRF in the MCP Client. An attacker can access internal or otherwise restricted network resources by supplying crafted endpoints, causing the server to connect to unintended host...

GHSA-VHF8-CG2H-CG3P n8n: SSRF Protection Bypass via MCP Client Node

Impact On an n8n instance with SSRF protection enabled, the MCP Client node sent requests to a user-supplied endpoint without routing them through that protection and without pinning the resolved address.

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal via improper validation of file paths in SVG images encoded as data-URI. An attacker can access arbitrary files from the server's filesystem by embedding a reference to a local file within a base64-encoded SVG image,...

Dompdf: File existence oracle via font-face stylesheet declaration

Description Dompdf is vulnerable to a File Existence Oracle attack through the manipulation of the CSS @font-face directive. By providing malicious HTML that references local files via the file:// protocol repeatedly, an attacker can trigger PHP memory exhaustion. The critical point of this flaw ...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal through improper validation in the validateLocalUri function. An attacker can access files outside of intended directory restrictions by crafting file paths that exploit prefix-based chroot checks. Details A Director...
