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.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CISA KEV (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2 Nov 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.

AI-suggested

Google has released an official patch addressing CVE-2022-2856 as part of a stable channel update that fixes 11 vulnerabilities. Users and administrators should apply the latest Chrome update promptly to mitigate this actively exploited zero-day. Google withheld detailed vulnerability information until the patch was widely deployed to reduce exploitation risk. No additional mitigation steps are indicated beyond applying the official update.

Description

Google patched a zero-day vulnerability in Chrome (CVE-2022-2856) related to insufficient validation of untrusted input in the Intents feature on Android. This flaw could allow arbitrary code execution and was actively exploited before the patch. The update included fixes for 11 vulnerabilities, with this being the fifth zero-day Chrome patch of the year. Google withheld detailed technical information until the patch was widely deployed to reduce risk. The vulnerability affects Chrome's handling of Intents, a deep linking mechanism replacing URI schemes on Android devices.

Impact

The vulnerability allows an attacker to execute arbitrary code on affected systems by exploiting insufficient input validation in Chrome's Intents feature on Android. This could lead to full compromise of the browser process or potentially the underlying system depending on the exploit context. The flaw was actively exploited in the wild prior to patching, increasing risk to users who had not yet updated. Since Intents handle deep linking to mobile apps, exploitation could be triggered via crafted links or web content.
