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 5 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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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.

What to do

Upgrade Google Chrome to 134.0.6998.35.

AI-suggested

To mitigate CVE-2025-1919, organizations should immediately update all instances of Google Chrome to version 134.0.6998.35 or later, where the vulnerability is patched. Enterprises should enforce browser update policies and use centralized management tools to ensure rapid deployment of the fix. Network defenses such as web filtering and intrusion prevention systems should be configured to block access to known malicious sites and suspicious HTML content that could exploit this vulnerability. Employing endpoint detection and response (EDR) solutions can help identify anomalous browser behavior indicative of exploitation attempts. User education is critical to reduce risky behaviors like visiting untrusted websites or clicking unknown links. Additionally, organizations should consider sandboxing browsers and limiting browser privileges to reduce potential impact. Monitoring threat intelligence feeds for emerging exploit attempts related to this CVE will aid in proactive defense. Finally, maintaining up-to-date backups and incident response plans will help mitigate damage if exploitation occurs.

Description

Out of bounds read in Media in Google Chrome prior to 134.0.6998.35 allowed a remote attacker to potentially perform out of bounds memory access via a crafted HTML page. (Chromium security severity: Medium)

Impact

The potential impact of CVE-2025-1919 is substantial for organizations worldwide. Successful exploitation could allow attackers to execute arbitrary code within the context of the browser, leading to full compromise of the user's session and potentially the underlying system, depending on sandboxing effectiveness. Confidential data accessed through the browser, such as credentials, personal information, or corporate data, could be exposed or manipulated. The integrity of web sessions and data could be compromised, enabling further attacks like phishing or lateral movement within networks. Availability could also be affected if exploitation causes browser crashes or system instability. Given Chrome's dominant market share in enterprise and consumer environments, the vulnerability poses a widespread risk. Attackers could weaponize this flaw in targeted attacks against high-value individuals or organizations, or in mass exploitation campaigns. The lack of known exploits currently provides a window for mitigation, but the ease of exploitation and high impact necessitate urgent remediation to prevent future attacks.
