What is CVE-2025-13016?

CVE-2025-13016 is a vulnerability found in the WebAssembly component of Firefox and related products, including Thunderbird. This vulnerability stems from incorrect boundary conditions in the JavaScript: WebAssembly module. The flaw is particularly critical as it impacts versions of Firefox prior to 145 and Firefox ESR (Extended Support Release) under 140.5, as well as Thunderbird versions lower than 145 and its ESR version lower than 140.5. If exploited, this vulnerability could lead to various negative consequences for organizations, including but not limited to compromised web navigation and severe security breaches, rendering user data and systems vulnerable to attack.

Potential impact of CVE-2025-13016

1. Security Breach Risk: The vulnerability exposes systems to potential exploitation, paving the way for unauthorized access to sensitive data or system controls. This can compromise organizational security and lead to significant data losses.

2. Denial of Service (DoS): Attackers could leverage this vulnerability to destabilize services, resulting in interruptions or complete denial of service for users relying on affected applications, ultimately impacting business continuity.

3. Increased Attack Surface: As WebAssembly becomes more integrated into web applications, vulnerabilities like CVE-2025-13016 may be targeted by malicious actors, increasing the likelihood of further attacks on organizational infrastructure and processes.
