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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, 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: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Disclosed: evidence found.
CVE published 10 Nov 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: 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 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

To mitigate this threat, European organizations should immediately update all Chrome installations to version 142 or later, which contains the patch for CVE-2025-12725. Where possible, disable or restrict WebGPU usage through browser policies or enterprise configuration management to reduce exposure, especially in high-risk environments. Employ network security controls such as web filtering and intrusion detection systems to monitor and block access to malicious websites that could host exploit code. Implement endpoint protection solutions capable of detecting anomalous behavior indicative of exploitation attempts. Regularly audit and enforce strict patch management policies to ensure timely application of browser updates. Educate users about the risks of visiting untrusted websites and encourage cautious browsing habits. For organizations with advanced security operations, consider deploying sandboxing or browser isolation technologies to contain potential exploits. Finally, maintain vigilance for threat intelligence updates regarding active exploitation attempts to adjust defenses accordingly.

Description

An out-of-bounds write flaw in WebGPU tracked as CVE-2025-12725 could be exploited for remote code execution. The post Chrome 142 Update Patches High-Severity Flaws appeared first on SecurityWeek .

Impact

For European organizations, the impact of this vulnerability is substantial. Given Chrome's dominant market share as a web browser in Europe, a large number of users and enterprise environments are exposed. Successful exploitation could lead to remote code execution, allowing attackers to gain unauthorized access to sensitive data, deploy malware, or disrupt operations. This threatens confidentiality by exposing private information, integrity by enabling unauthorized modifications, and availability by potentially causing system crashes or ransomware deployment. Organizations in sectors such as finance, government, healthcare, and critical infrastructure, which rely heavily on secure web access, face heightened risks. Additionally, the WebGPU feature is increasingly used in advanced web applications, including data visualization and interactive services, expanding the attack surface. The absence of known exploits currently provides a window for proactive defense, but the critical nature of the flaw means that delayed patching could lead to rapid exploitation once public proof-of-concept code or weaponized exploits emerge.
