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.
Exploit Code Maturity: Unproven: No exploit code is available, or an exploit is theoretical.
Remediation Level: Official Fix: A complete vendor solution is available. Either the vendor has issued an official patch, or an upgrade is available.
Report Confidence: Confirmed: Detailed reports exist, or functional reproduction is possible (functional exploits may provide this). Source code is available to independently verify the assertions of the research, or the author or vendor of the affected code has confirmed the presence of the vulnerability.

Exploitation evidence

Disclosed: evidence found.
CVE published 11 Jul 2025
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
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 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.

AI-suggested

Monitor for official patches or updates from Microsoft and apply them immediately once available to remediate the vulnerability.
Until patches are released, implement browser security policies that restrict or monitor the execution of untrusted scripts and content, such as enabling strict Content Security Policies (CSP).
Educate users about the risks of phishing and UI spoofing attacks, emphasizing caution when interacting with unexpected links or requests for sensitive information.
Employ multi-factor authentication (MFA) across critical systems to reduce the impact of credential compromise resulting from spoofing attacks.
Use endpoint protection solutions that can detect and block malicious web content or suspicious browser behavior.
Consider deploying browser extensions or security tools that enhance UI integrity verification, such as indicators that confirm site authenticity beyond the standard address bar.
Network-level defenses like web proxies or secure web gateways can help filter malicious sites and reduce exposure.
Regularly audit browser versions across the organization to ensure no outdated or vulnerable versions remain in use.
Encourage users to verify URLs manually and look for inconsistencies in browser UI elements when accessing sensitive sites.
Maintain incident response readiness to quickly address any phishing or spoofing incidents that may arise.

Description

Microsoft Edge (Chromium-based) Spoofing Vulnerability

Impact

The primary impact of CVE-2025-47964 is on the confidentiality and integrity of user data. By spoofing critical UI elements, attackers can trick users into divulging sensitive information such as login credentials, personal data, or financial details. This can lead to account compromise, identity theft, or unauthorized access to corporate resources. The vulnerability does not affect system availability, so denial-of-service is not a concern here. However, the erosion of user trust in browser security indicators can have broader implications for organizational security postures, especially in sectors relying heavily on secure web transactions, such as finance, healthcare, and e-commerce. Since exploitation requires user interaction, the risk is somewhat mitigated by user awareness but remains significant in environments where phishing attacks are prevalent. Organizations worldwide using Microsoft Edge Chromium-based browsers, particularly those with outdated versions, are at risk. The lack of known exploits in the wild currently reduces immediate threat levels but does not preclude future exploitation once weaponized. The medium CVSS score reflects a moderate risk that should be addressed promptly to prevent potential data breaches and fraud.
