Exploitation evidence

Disclosed: evidence found.
CVE published 20 Jan 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade nodejs to 20.20.1.

AI-suggested

Red Hat has released an official security update for the Node.js 20 module in Red Hat Enterprise Linux 9 that addresses these vulnerabilities. Users should apply the update as described in the Red Hat advisory (RHSA-2026:2783) available at https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official patch.

Description

Node.js is a software development platform for building fast and scalable network applications in the JavaScript programming language. Security Fix(es): * nodejs: Nodejs filesystem permissions bypass (CVE-2025-55132) * nodejs: Nodejs denial of service (CVE-2026-21637) * nodejs: Nodejs denial of service (CVE-2025-59466) * nodejs: Nodejs denial of service (CVE-2025-59465) * nodejs: Nodejs uninitialized memory exposure (CVE-2025-55131) * nodejs: Nodejs file permissions bypass (CVE-2025-55130) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Impact

The vulnerabilities could allow unauthorized bypass of filesystem permissions, cause denial of service conditions, or expose uninitialized memory, potentially leading to information disclosure or service disruption. The severity is rated as high by the source data, indicating significant risk if unpatched. There are no known exploits in the wild at this time.

Summary

This advisory covers six security vulnerabilities in the Node.js 20 module for Red Hat Enterprise Linux 9, including CVE-2025-55130 and related CVEs. The issues include filesystem permissions bypass (CWE-281), denial of service (CWE-770), and uninitialized memory exposure (CWE-248), among others. Red Hat has released an update to fix these vulnerabilities, which affect multiple architectures and extended support versions of RHEL 9. The advisory does not provide CVSS scores but rates the update as important. The vendor advisory provides detailed instructions for applying the update.

CWE-281Improper Preservation of Permissions (opens in a new tab)
Base weaknessOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product does not preserve permissions or incorrectly preserves permissions when copying, restoring, or sharing objects, which can cause them to have less restrictive permissions than intended.

Base weaknessOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product does not properly prevent sensitive system-level information from being accessed by unauthorized actors who do not have the same level of access to the underlying system as the product does.
Architecture and Design · Implementation
Production applications should never use methods that generate internal details such as stack traces and error messages unless that information is directly committed to a log that is not viewable by the end user.

CWE-770Allocation of Resources Without Limits or Throttling (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #25
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
Requirements
Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.
Architecture and Design
Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended.
