Cisco Addresses ISE Vulnerability; HPE OneView Under Threat; Exploit Code Emerges for n8n Flaw
As 2026 unfolds, a surge of vulnerabilities is prompting urgent responses from IT administrators who face the challenge of implementing timely security patches. Cisco has recently issued software updates to address a zero-day vulnerability in its latest security platform that could expose sensitive data.
In a separate issue, cybersecurity agencies have alerted organizations about active exploitation of a flaw in Hewlett Packard Enterprise’s IT infrastructure management software, OneView, allowing attackers to execute remote code. This alarming situation emphasizes the necessity for vigilance in maintaining cybersecurity hygiene, especially as threats become increasingly sophisticated.
Additionally, after recent patches for a critical vulnerability in the n8n automation software, security experts have reported the emergence of proof-of-concept exploits associated with this flaw, portending potential widespread attacks on the open-source platforms used by around 100,000 servers globally.
Cisco’s Remedial Measures
Cisco has issued an advisory regarding a vulnerability affecting its Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC). The security flaw, associated with the licensing features, could allow an authenticated remote attacker with administrative privileges to access sensitive information. Proper XML parsing issues within the web interface contribute to this vulnerability, which is logged as CVE-2026-20029.
Notably, this vulnerability is present in all versions of ISE prior to the release of version 3.5 in September 2025. Attackers could potentially exploit this flaw to read unauthorized files from the underlying operating system, thereby putting sensitive information at risk. While no exploits have been observed in the wild, Cisco’s product security team remains vigilant, acknowledging that exploit code has been made public.
Threats to HPE OneView
The U.S. Cybersecurity and Infrastructure Security Agency has informed that the vulnerability in HPE OneView, designated as CVE-2025-37164, is currently being actively exploited. This severe flaw, which affects all versions prior to 11.00, can enable remote unauthenticated code execution. Organizations utilizing the affected software are urged to apply the necessary patches and update their systems promptly.
Implications of the n8n Vulnerability
Users of the open-source n8n platform are now urged to upgrade to the latest version, which addresses a significant vulnerability dubbed “Ni8mare.” This flaw allows unauthorized remote code execution on installed instances, potentially impacting numerous businesses that depend on this software for automation tasks. The vulnerability is underscored by a critical CVSS score of 10, prompting urgent action from affected users.
As organizations continue to integrate automation solutions like n8n into their operations, the risks associated with such vulnerabilities cannot be underestimated. The interconnected nature of modern enterprise ecosystems means that a compromised instance could expose critical resources, posing significant security threats. Cybersecurity best practices involve ensuring that only necessary endpoints are exposed and that authentication measures are rigorously enforced.
In the ever-evolving landscape of cyber threats, business owners must remain not only aware but also proactive in addressing these vulnerabilities across their systems to safeguard sensitive data and maintain the integrity of their technological infrastructure. The identified vulnerabilities and their implications can be cross-referenced with the MITRE ATT&CK framework, highlighting tactics such as initial access and privilege escalation as potential attack vectors relevant to the ongoing threats.
