View the latest critical CVEs issued
This is a free service offered by Red Hot Cyber to the community. It allows you to view, on a single page, information about a single CVE from the National Vulnerability Database (NVD) and the National Institute of Standards and Technology (NIST) of the United States of America, the Forum of Incident Response and Security Teams (FIRST) regarding the EPSS score and percentile, data from the KEV catalog of the Cybersecurity and Infrastructure Security Agency (CISA), as well as selected resources from Red Hot Cyber and other international sources.

National Vulnerability Database Information

Description: n8n is an open source workflow automation platform. Prior to versions 1.123.9 and 2.2.1, a Cross-Site Scripting (XSS) vulnerability existed in a markdown rendering component used in n8n's interface, including workflow sticky notes and other areas that support markdown content. An authenticated user with permission to create or modify workflows could abuse this to execute scripts with same-origin privileges when other users interact with a maliciously crafted workflow. This could lead to session hijacking and account takeover. This issue has been patched in versions 1.123.9 and 2.2.1.

CVSS Base Score: 5.4 (v3.1)

The **CVSS Base Score** is a score from **0 to 10** that represents the intrinsic severity of a vulnerability. A higher score indicates greater severity.

Common Weakness Enumeration (CWE)

Database CWE: v4.18

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') ↗

The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.

CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) ↗

The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages.

FIRST Information

EPSS Score: 0.0001

The **EPSS (Exploit Prediction Scoring System)** is a score from **0 to 1** that indicates the **probability** that a vulnerability will be exploited in the real world in the next 30 days. A higher value indicates a greater likelihood of exploitation.

Value
0.00.250.50.751.0

Percentile: 0.0232

The **Percentile** indicates how much higher this vulnerability's EPSS score is compared to all other vulnerabilities in the EPSS database. For example, a percentile of 0.90 (90%) means that 90% of vulnerabilities have an EPSS score equal to or lower than the current one.

Value
0.00.250.50.751.0

*Data updated as of: 2026-04-13


CISA Information (Known Exploited Vulnerabilities)

The **CISA KEV Catalog** lists vulnerabilities that have been **actively exploited in the real world**. If a CVE is present in this catalog, it indicates that the threat is immediate and mitigation should be a top priority.

CVE **CVE-2026-25054** is not present in the CISA KEV Catalog. This indicates that it is not currently classified by CISA as an actively exploited vulnerability.
