Summary
A vulnerability was found in makafeli n8n-workflow-builder up to version 0.11.0 in the update_node_from_file function of build/server.cjs. Manipulating the filePath argument allows path traversal, requiring local access. The exploit is publicly available and the project has not responded to the report.
Risk Assessment
An attacker with local access can read or overwrite arbitrary files on the system, compromising data confidentiality and integrity.
Recommendation
Immediately block access to the vulnerable version (up to 0.11.0) and apply temporary restrictions on local server access. Monitor the public repository for a patch.

KEDA is a Kubernetes-based Event Driven Autoscaling component. In version 2.20.2 and earlier, a namespace administrator who can create TriggerAuthentication and ScaledObject resources can set hashiCorpVault.address to a tenant-controlled endpoint and select Kubernetes authentication without an explicit credential. KEDA then uses the operator pod's projected ServiceAccount token and sends it to that endpoint as a Vault login credential; the JWT-shape filter from the prior CVE-2025-68476 remediation accepts the operator token because its subject is a Kubernetes ServiceAccount, allowing the attacker to obtain the operator's cluster-wide permissions, including broad Secret reads and workload or admission-related operations.

A vulnerability in the Advanced Malware Protection (AMP) feature of Cisco Secure Email Gateway could allow an unauthenticated, remote attacker to write arbitrary files on the underlying operating system. It is due to improper handling of email attachments when the file reputation service is enabled; an attacker could send an email with a crafted attachment through an affected device, potentially allowing arbitrary file writes and command execution with root privileges.

A missing authentication vulnerability in Lantronix XPress-DR and XPress-DR-I (CoBos-family) firmware through 8.1.0.0 allows remote attackers to read and persistently overwrite device configuration by sending crafted frames to the unauthenticated UDP configuration protocol on port 30718. Attackers can send a type 0xF8 query to read live configuration data and a type 0xFD frame with exactly 0x78 body bytes to rewrite the device IP address and serial-channel forwarding records, causing changes to commit to EEPROM and persist across reboots. The XPress-DR product series reached end-of-life/end-of-support in February 2025.

Original NVD description (English source)
A vulnerability was identified in makafeli n8n-workflow-builder up to 0.11.0. Affected is an unknown function of the file build/server.cjs of the component update_node_from_file. The manipulation of the argument filePath leads to path traversal. An attack has to be approached locally. The exploit is publicly available and might be used. The project was informed of the problem early through an issue report but has not responded yet.
