CVE-2025-13022 identifies a security vulnerability in the Mozilla Firefox browser, specifically affecting versions prior to 145. The issue lies within the Graphics: WebGPU component, where incorrect boundary conditions have been implemented. WebGPU is a modern web graphics API designed to provide high-performance 3D graphics and computation capabilities within web browsers. Incorrect boundary conditions typically refer to improper validation or handling of buffer sizes, array indices, or memory limits, which can lead to memory corruption, buffer overflows, or out-of-bounds reads/writes. Such memory corruption vulnerabilities can be exploited by attackers to execute arbitrary code, escalate privileges, or cause denial of service by crashing the browser. Although no known exploits have been reported in the wild at the time of publication, the nature of the vulnerability suggests that exploitation could be achieved by crafting malicious web content that leverages WebGPU features. Firefox is widely used across various platforms, and this vulnerability affects all users running versions older than 145. The lack of a CVSS score indicates that the vulnerability is newly disclosed and pending further analysis. Mozilla is expected to release patches addressing this issue, but until then, users remain exposed. The vulnerability's exploitation requires no authentication but does require user interaction in the form of visiting a malicious or compromised website that uses WebGPU. This increases the attack surface significantly, especially for organizations with employees browsing the internet using vulnerable Firefox versions. The technical details are limited, but the core issue revolves around boundary condition errors in a critical graphics subsystem, which historically have been high-risk due to their potential for arbitrary code execution.

For European organizations, the impact of CVE-2025-13022 could be significant. Firefox is a popular browser in Europe, used both in private and enterprise environments. Exploitation of this vulnerability could lead to unauthorized code execution within the browser context, potentially allowing attackers to steal sensitive information, deploy malware, or move laterally within corporate networks. The WebGPU component's role in rendering graphics means that exploitation might bypass some traditional sandboxing or security controls, increasing risk. Additionally, denial of service attacks could disrupt business operations by crashing browsers or systems. Organizations in sectors such as finance, government, healthcare, and critical infrastructure, which rely heavily on secure web browsing, could face increased risk. The lack of known exploits currently provides a window for proactive mitigation, but the vulnerability's nature demands urgent attention. The potential for exploitation via web content means that phishing or drive-by download attacks could be vectors, increasing exposure. Overall, the vulnerability threatens confidentiality, integrity, and availability of systems using affected Firefox versions.

To mitigate CVE-2025-13022, European organizations should implement the following specific measures: 1) Monitor Mozilla security advisories closely and apply Firefox updates promptly once patches for this vulnerability are released. 2) Temporarily disable or restrict the use of WebGPU features in Firefox via browser configuration policies or enterprise management tools to reduce attack surface until patched. 3) Employ web content filtering and URL reputation services to block access to potentially malicious websites that could exploit this vulnerability. 4) Educate users about the risks of visiting untrusted websites and the importance of keeping browsers updated. 5) Use endpoint protection solutions capable of detecting anomalous browser behavior or exploitation attempts related to memory corruption. 6) Consider deploying browser isolation technologies for high-risk users to contain potential exploitation. 7) Conduct internal vulnerability scanning and penetration testing to identify any exposure to this vulnerability in organizational environments. These targeted actions go beyond generic advice by focusing on controlling WebGPU usage, enhancing detection, and prioritizing patch management.
