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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
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 on 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), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

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 143.0.7499.110.

AI-suggested

1. Immediately update all Google Chrome installations to version 143.0.7499.110 or later, as this version contains the fix for CVE-2025-14372. 2. Implement strict Content Security Policies (CSP) to restrict the execution of untrusted scripts and reduce the risk of malicious HTML pages triggering the vulnerability. 3. Educate users about the risks of visiting untrusted websites and clicking on unknown links to minimize user interaction exploitation vectors. 4. Employ endpoint detection and response (EDR) solutions capable of detecting unusual sandbox escape behaviors or exploitation attempts. 5. Regularly audit browser extensions and plugins to ensure they do not introduce additional vulnerabilities or weaken sandbox protections. 6. 7. Consider network-level protections such as web filtering to block access to known malicious sites that could host exploit pages. 8. For high-risk environments, consider isolating browser processes or using dedicated browsing environments to limit potential damage from exploitation.

Description

CVE-2025-14372 is a use-after-free vulnerability in the Password Manager component of Google Chrome versions prior to 143.0.7499.110. This flaw allows a remote attacker to potentially escape the browser sandbox by crafting a malicious HTML page. The vulnerability has a CVSS score of 6.1, indicating medium severity, with impacts on confidentiality and integrity but no direct availability impact. Exploitation requires user interaction, such as visiting a malicious webpage, and no privileges are needed. There are no known exploits in the wild currently. European organizations using vulnerable Chrome versions could face risks of credential theft or further system compromise if exploited.

Impact

For European organizations, exploitation of this vulnerability could lead to unauthorized access to sensitive information stored in the browser's password manager, undermining confidentiality. A successful sandbox escape could allow attackers to execute arbitrary code on the host system, potentially leading to broader system compromise, data theft, or lateral movement within corporate networks. This risk is particularly concerning for organizations with employees who frequently use Chrome for web access, especially in sectors handling sensitive data such as finance, healthcare, and government. The medium severity rating reflects that while exploitation requires user interaction, the consequences of a sandbox escape can be severe. Additionally, the widespread use of Chrome in Europe increases the potential attack surface. However, the absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat. Organizations relying on Chrome should consider this vulnerability a significant security concern.

CWE-416Use After Free (opens in a new tab)
Variant weaknessLikelihood of exploit: HighCWE Top 25 (2025): #7
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
Architecture and Design · Language Selection
Choose a language that provides automatic memory management.
Implementation · Attack Surface Reduction
When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
