The vulnerability of the Buffer.allocUnsafe() and Buffer.allocUnsafeSlow() functions on the n8n platform, which allow attackers to disclose protected information.

The vulnerability of the Buffer.allocUnsafe and Buffer.allocUnsafeSlow functions in the n8n automation platform relates to the disclosure of information. Exploiting this vulnerability can allow a remote attacker to disclose the protected information...

CVE-2025-8860

A flaw was found in QEMU in the uefi-vars virtual device. When the guest writes to register UEFIVARSREGBUFFERSIZE, the .write callback uefivarswrite is invoked. The function allocates a heap buffer without zeroing the memory, leaving the buffer filled with residual data from prior allocations. Wh...

nodejs: Nodejs uninitialized memory exposure

A memory exposure flaw has been discovered in Node.js. A flaw in Node.js's buffer allocation logic can expose uninitialized memory when allocations are interrupted, when using the vm module with the timeout option. Under specific timing conditions, buffers allocated with Buffer.alloc and other...

Use of Uninitialized Resource

Overview Affected versions of this package are vulnerable to Use of Uninitialized Resource via the Buffer.allocUnsafe and Buffer.allocUnsafeSlow functions in the task runner process. An attacker can access sensitive in-process memory contents by executing untrusted code that allocates uninitializ...

GHSA-49MX-FJ45-Q3P6 n8n's Unsafe Buffer Allocation Allows In-Process Memory Disclosure in Task Runner

Impact The use of Buffer.allocUnsafe and Buffer.allocUnsafeSlow in the task runner allowed untrusted code to allocate uninitialized memory. Such uninitialized buffers could contain residual data from within the same Node.js process for example, data from prior requests, tasks, secrets, or tokens,...
