Cybersecurity researchers have disclosed details of yet another maximum-severity security flaw in n8n, a popular workflow automation platform, that allows an unauthenticated remote attacker to gain complete control over susceptible instances. The vulnerability, tracked as CVE-2026-21858 (CVSS score: 10.0), has been codenamed Ni8mare by Cyera Research Labs. Security researcher Dor Attias has been

OpenFlagr versions prior to and including 1.1.18 contain an authentication bypass vulnerability in the HTTP middleware.

A weakness has been identified in carboneio carbone up to fbcd349077ad0e8748be73eab2a82ea92b6f8a7e. This impacts an unknown function of the file lib/input.js of the component Formatter Handler. Executing a manipulation can lead to improperly controlled modification of object prototype attributes. The attack can be launched remotely. This attack is characterized by high complexity. The exploitability is said to be difficult. Upgrading to version 3.5.6 will fix this issue. This patch is called 04f9feb24bfca23567706392f9ad2c53bbe4134e. You should upgrade the affected component. A successful exploitation can "only occur if the parent NodeJS application has the same security issue".
