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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
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: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Disclosed: evidence found.
CVE published 10 Mar 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 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

To mitigate CVE-2025-1920, organizations should immediately prioritize updating Google Chrome to version 134.0.6998.88 or later once available. Until patches are applied, consider implementing the following measures: 1) Employ browser isolation technologies to sandbox web content and limit the impact of potential exploits. 2) Use enterprise browser management tools to enforce automatic updates and restrict installation of unapproved extensions or plugins that could increase attack surface. 3) Configure Content Security Policy (CSP) headers on internal web applications to reduce the risk of malicious script execution. 4) Educate users about the risks of visiting untrusted websites and clicking on unknown links to reduce the likelihood of triggering the vulnerability. 5) Deploy endpoint detection and response (EDR) solutions capable of detecting anomalous browser behavior indicative of exploitation attempts. 6) Where feasible, disable or restrict JavaScript execution in high-risk environments or for users with elevated privileges. 7) Monitor security advisories from Google and Chromium for any updates or additional patches related to this vulnerability. These steps, combined with timely patching, will significantly reduce the risk posed by this vulnerability.

Description

Type Confusion in V8 in Google Chrome prior to 134.0.6998.88 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

Impact

The potential impact of CVE-2025-1920 is significant for organizations worldwide due to the widespread use of Google Chrome as a primary web browser. Successful exploitation could lead to arbitrary code execution within the browser context, allowing attackers to bypass security controls, execute malicious payloads, and potentially pivot to internal networks. Confidentiality could be compromised through data theft such as cookies, session tokens, or other sensitive information accessible via the browser. Integrity could be affected by unauthorized modification of data or web content. Availability could be disrupted by crashes or denial-of-service conditions caused by heap corruption. Given the remote and unauthenticated nature of the exploit, combined with the requirement for only user interaction, the attack surface is broad. Organizations with employees or users who frequently browse the internet are at risk, especially those in sectors with high-value targets such as finance, government, healthcare, and critical infrastructure. The vulnerability also poses risks to end users, potentially enabling drive-by downloads of malware or ransomware. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, as attackers often develop exploits rapidly after public disclosure.
