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: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 11 Mar 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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 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 Google Chrome to 146.0.7680.71.

AI-suggested

To mitigate CVE-2026-3930, organizations and users should promptly update Google Chrome on iOS devices to version 146.0.7680.71 or later, where the vulnerability has been addressed. Beyond patching, organizations should implement strict web content filtering and URL filtering to block access to known malicious sites and reduce exposure to crafted HTML pages designed to exploit navigation flaws. Employing mobile device management (MDM) solutions to enforce browser updates and restrict installation of unapproved browsers can further reduce risk. User education is critical: training users to recognize suspicious links and avoid clicking on untrusted URLs can limit successful exploitation. Additionally, monitoring network traffic for unusual redirection patterns or anomalous browsing behavior may help detect exploitation attempts. Organizations should also consider deploying endpoint protection solutions capable of detecting browser-based attacks and enforcing security policies on iOS devices. Regular vulnerability scanning and penetration testing focused on mobile browsers can help identify residual risks.

Description

Unsafe navigation in Navigation in Google Chrome on iOS prior to 146.0.7680.71 allowed a remote attacker to bypass navigation restrictions via a crafted HTML page. (Chromium security severity: Medium)

Impact

The primary impact of CVE-2026-3930 is on the integrity of user navigation within Google Chrome on iOS devices. Attackers exploiting this vulnerability can bypass navigation restrictions, potentially redirecting users to malicious or unintended websites without their consent. This can facilitate phishing attacks, malware distribution, or other social engineering exploits that rely on manipulating user navigation. While confidentiality and availability are not directly affected, the integrity compromise can lead to significant security risks, especially for organizations relying on Chrome on iOS for secure browsing or sensitive transactions. The requirement for user interaction limits automated exploitation but does not eliminate risk, as users may be tricked into visiting malicious pages. Organizations with large iOS user bases or those in sectors such as finance, healthcare, or government where secure browsing is critical may face increased risk. The absence of known exploits in the wild reduces immediate threat but does not preclude future attacks. Failure to patch could expose users to targeted or opportunistic attacks leveraging this vulnerability.
