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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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.
Not in CISA KEV and no source reports exploitation

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 2026-10-26.

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 Google Chrome to 144.0.7559.59.

AI-suggested

1. Immediately update all Google Chrome installations to version 144.0.7559.59 or later to apply the security fix. 2. Implement enterprise-wide browser update policies to ensure timely patching of vulnerabilities. 3. Educate users on recognizing phishing attempts and verifying website authenticity beyond browser UI cues, including checking URLs carefully and using multi-factor authentication. 4. Deploy web filtering solutions that can block access to known malicious sites and suspicious URLs. 5. Monitor network traffic for unusual patterns that may indicate phishing or spoofing attempts. 6. Encourage the use of password managers that autofill credentials only on verified domains to reduce the risk of credential theft. 7. Conduct regular security awareness training emphasizing the risks of UI spoofing and social engineering. 8. For critical systems, consider browser isolation or sandboxing technologies to limit exposure to malicious web content.

Description

Incorrect security UI in Digital Credentials in Google Chrome prior to 144.0.7559.59 allowed a remote attacker to perform domain spoofing via a crafted HTML page. (Chromium security severity: Medium)

Impact

For European organizations, this vulnerability poses a risk primarily through phishing and social engineering attacks that exploit the browser's UI to spoof trusted domains. This can lead to unauthorized disclosure of sensitive information, credential compromise, and potential downstream impacts such as unauthorized access to corporate resources or financial fraud. Organizations with employees who frequently access web-based services or handle sensitive data via Chrome browsers are particularly vulnerable. The impact on confidentiality and integrity is significant, as attackers can deceive users into submitting credentials or sensitive data to malicious sites. Availability is less directly impacted, but successful exploitation could lead to broader security incidents affecting service continuity. The lack of known exploits in the wild reduces immediate risk, but the widespread use of Chrome in Europe and the reliance on digital credentials heighten the potential impact if exploited. Regulatory compliance frameworks such as GDPR also increase the importance of addressing such vulnerabilities promptly to avoid data breaches and associated penalties.

Class weaknessOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The user interface (UI) does not properly represent critical information to the user, allowing the information - or its source - to be obscured or spoofed. This is often a component in phishing attacks.
