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.
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 12 Aug 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

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.

AI-suggested

1. Monitor official Microsoft security advisories for patches addressing CVE-2025-49736 and apply updates promptly once available. 2. Until patches are released, restrict or limit the use of Microsoft Edge for Android in sensitive environments or on devices handling critical data. 3. Implement mobile device management (MDM) solutions to enforce browser usage policies and control app updates. 4. Educate users about the risk of spoofed UI elements and encourage vigilance when interacting with unexpected or suspicious browser prompts or actions. 5. Employ network-level protections such as DNS filtering and secure web gateways to block access to known malicious sites that could exploit this vulnerability. 6. Encourage the use of multi-factor authentication (MFA) to reduce the impact of potential credential theft resulting from spoofing. 7. Conduct regular security awareness training focusing on phishing and social engineering tactics that may leverage UI spoofing. 8. Consider alternative browsers with a strong security track record on Android until this vulnerability is resolved.

Description

The ui performs the wrong action in Microsoft Edge for Android allows an unauthorized attacker to perform spoofing over a network.

Impact

For European organizations, this vulnerability poses a moderate risk, especially for those with employees using Microsoft Edge on Android devices. The spoofing capability can lead to users being tricked into divulging sensitive information or executing unintended actions, potentially compromising data integrity or enabling further attacks such as credential theft or malware installation. While confidentiality and availability are not directly impacted, the integrity loss can cascade into broader security incidents. Organizations with mobile workforces or BYOD policies are particularly vulnerable. The risk is heightened in sectors with high security requirements such as finance, healthcare, and government, where spoofed UI actions could lead to unauthorized transactions or data manipulation. The lack of a patch increases exposure time, and the requirement for user interaction means that user awareness and training are critical. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for future exploitation.
