Confidentiality: None
Integrity: Low
Availability: None

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: None: There is no loss of confidentiality within 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 11 Feb 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 2026-10-25.

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 145.0.7632.45.

AI-suggested

To mitigate CVE-2026-2323, organizations should prioritize updating Google Chrome to version 145.0.7632.45 or later, where the vulnerability is addressed. In environments where immediate patching is not feasible, deploying browser security policies to restrict or monitor downloads and block untrusted content can reduce exposure. User education is critical; training users to recognize suspicious UI elements and avoid interacting with untrusted links or downloads can prevent exploitation. Employing endpoint protection solutions with phishing detection capabilities can provide additional defense layers. Network-level controls such as web filtering and sandboxing of downloads can help detect and block malicious HTML pages designed to exploit this vulnerability. Security teams should monitor threat intelligence feeds for any emerging exploit attempts. Finally, organizations should enforce multi-factor authentication and robust incident response plans to mitigate potential fallout from successful phishing attacks leveraging this UI spoofing vulnerability.

Description

Inappropriate implementation in Downloads in Google Chrome prior to 145.0.7632.45 allowed a remote attacker to perform UI spoofing via a crafted HTML page. (Chromium security severity: Low)

Impact

The primary impact of CVE-2026-2323 is on the integrity of the user interface within Google Chrome, enabling attackers to deceive users through UI spoofing. This can facilitate phishing attacks, tricking users into divulging sensitive information, downloading malware, or performing unintended actions under false pretenses. While the vulnerability does not directly compromise confidentiality or availability, the indirect consequences of successful social engineering can lead to credential theft, unauthorized access, or malware infection. Organizations with employees or customers using vulnerable Chrome versions face increased risk of targeted phishing campaigns leveraging this flaw. The widespread use of Chrome across enterprises, governments, and consumers globally amplifies the potential impact. However, the requirement for user interaction and the absence of privilege escalation limit the severity compared to more critical vulnerabilities. No known active exploitation reduces immediate risk but does not eliminate future threats once exploit code becomes available.
