Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Exploitation evidence

Disclosed: evidence found.
CVE published 29 Oct 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: 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 2 Nov 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity 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

AI-suggested

Red Hat has released updated RPM packages for nodejs24 and related components that fix this vulnerability. Users should apply these security updates as soon as possible to remediate the issue. No other mitigations or workarounds are specified by Red Hat.

Description

A vulnerability (CVE-2026-118764) was found in the minimatch component used in Red Hat Hardened Images RPMs, specifically affecting nodejs24 packages. The flaw allows a remote attacker to cause a Denial of Service (DoS) by supplying a specially crafted glob pattern that triggers excessive CPU and memory consumption during pattern compilation. This leads to resource exhaustion. Red Hat has released updated RPM packages to address this issue.

Impact

The vulnerability allows remote attackers to cause a denial of service via resource exhaustion (high CPU and memory consumption) by supplying malicious glob patterns. This can disrupt availability of affected systems running the vulnerable nodejs24 packages in Red Hat Hardened Images. There is no impact on confidentiality or integrity reported.

Summary

CVE-2026-118764 is a denial of service vulnerability in the minimatch library used by nodejs24 RPMs in Red Hat Hardened Images. The vulnerability arises from unchecked input for loop conditions (CWE-606), where a crafted glob expression causes repetitive pattern segment expansion at higher optimization levels, resulting in excessive CPU and memory usage. Red Hat has issued updated RPM packages (version 24.22.2-0.2.hum1 and related) that fix this issue. The vulnerability has a Red Hat CVSS v3 score of 7.5 (high severity) and does not require privileges or user interaction to exploit.

CWE-606Unchecked Input for Loop Condition (opens in a new tab)
Base weakness
The product does not properly check inputs that are used for loop conditions, potentially leading to a denial of service or other consequences because of excessive looping.
Implementation
Do not use user-controlled data for loop conditions.
Implementation
Perform input validation.
