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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: Active: Successful exploitation of this vulnerability requires a targeted user to perform specific, conscious interactions with the vulnerable system and the attacker’s payload, or the user’s interactions would actively subvert protection mechanisms which would lead to exploitation of the vulnerability.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system 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 to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

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 30 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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

Upgrade Maxthon Browser for Android to 7.5.8.103.

AI-suggested

Users and administrators should update Maxthon Browser for Android to version 7.5.8.103 or later, where this vulnerability is fixed. Applying this official update eliminates the risk of address bar spoofing via the Fullscreen API. No additional mitigations are indicated by the vendor advisory.

Description

CVE-2026-119730 is an address bar spoofing vulnerability in Maxthon Browser for Android versions before 7.5.8.103. It allows remote attackers to misrepresent a page's origin by exploiting the absence of a persistent fullscreen notification or trusted origin indicator when the Fullscreen API is used. This can trick users into believing they are on a trusted domain while interacting with attacker-controlled content, potentially leading to credential disclosure via phishing.

Impact

The vulnerability enables remote attackers to perform address bar spoofing, misleading users about the true origin of the webpage they are viewing. This can facilitate phishing attacks that lead to credential theft. The CVSS 4.0 base score is 5.1 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and limited impact on integrity.

Summary

Maxthon Browser for Android versions prior to 7.5.8.103 contain a UI misrepresentation vulnerability involving the address bar. When a user activates fullscreen mode via the Fullscreen API, the browser fails to display a persistent notification or trusted origin indicator. An attacker can craft a malicious webpage that renders a fake address bar showing a trusted domain, while displaying attacker-controlled content underneath. This spoofing can deceive users into submitting credentials to the attacker, leveraging a single tap to enter fullscreen mode. The vulnerability is fixed in version 7.5.8.103.
