A use-after-free vulnerability exists in the Widget: Cocoa component of Mozilla Firefox and Thunderbird. The vulnerability stems from the program referencing memory after it has been freed. An attacker could exploit this vulnerability to cause the application to crash, read unexpected values, or execute arbitrary code, thereby affecting the confidentiality, integrity, and availability of the system. This vulnerability affects Firefox versions up to 149 and corresponding versions of Thunderbird.(CVE-2026-6759)
A privilege escalation vulnerability exists in the Networking component of Mozilla Firefox and Thunderbird. An attacker could potentially exploit this vulnerability to escalate privileges, which may lead to remote code execution, impacting confidentiality, integrity, and availability.

Spoofing issue in the DOM: Core & HTML component. This vulnerability was fixed in Firefox 150, Firefox ESR 115.35, Firefox ESR 140.10, Thunderbird 150, and Thunderbird 140.10.(CVE-2026-6762)
A mitigation bypass vulnerability exists in the File Handling component of Mozilla Firefox and Thunderbird. This vulnerability could allow an attacker to bypass security mitigations, potentially impacting the confidentiality, integrity, and availability of the system. According to VulDB, this vulnerability is rated as critical. Affected versions include Firefox up to version 149, Firefox ESR prior to 140.10, Thunderbird up to version 149, and Thunderbird ESR prior to 140.10.(CVE-2026-6763)
An incorrect boundary condition vulnerability exists in the DOM (Document Object Model) 'Device Interfaces' component of Mozilla Firefox and Thunderbird. This vulnerability is classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer), which is a memory corruption issue. An attacker could potentially exploit this by tricking a user into visiting a specially crafted web page, causing the application to read from or write to a memory location outside the intended boundary of a buffer. This impacts the confidentiality, integrity, and availability of the affected system.(CVE-2026-6764)
An information disclosure vulnerability (CWE-200) exists in the Form Autofill component of Mozilla Firefox. This vulnerability could allow sensitive information to be exposed to unauthorized actors, posing a threat to data confidentiality. This vulnerability affects Firefox versions up to 149, Firefox ESR versions prior to 140.10, Thunderbird versions up to 149, and Thunderbird ESR versions prior to 140.10.(CVE-2026-6765)
An incorrect boundary condition vulnerability exists in the Network Security Services (NSS) library used by Mozilla Firefox, Firefox ESR, and Thunderbird. An attacker could exploit this vulnerability to read from or write to a memory location outside the intended boundary of a buffer, leading to memory corruption. This could result in application crashes, denial of service, or potentially arbitrary code execution, threatening confidentiality, integrity, and availability.(CVE-2026-6766)
A security vulnerability exists in the Network Security Services (NSS) library used by Mozilla Firefox and Thunderbird.

This vulnerability affects Firefox versions up to 149, Firefox ESR versions prior to 140.10, Thunderbird versions up to 149, and Thunderbird ESR versions prior to 140.10. An attacker could potentially exploit this vulnerability to bypass certain security mechanisms, posing a threat to system integrity.(CVE-2026-6771)
An incorrect boundary conditions vulnerability (CWE-119) exists in the Network Security Services (NSS) library used by Mozilla Firefox. The vulnerability occurs when the product performs operations on a memory buffer, allowing it to read from or write to a memory location outside the intended boundary of the buffer, leading to memory corruption. This impacts confidentiality, integrity, and availability. Affected versions include Firefox up to 149, Firefox ESR prior to 115.35, Firefox ESR prior to 140.10, Thunderbird prior to 150, and Thunderbird prior to 140.10.(CVE-2026-6772)
An incorrect boundary conditions vulnerability exists in the WebRTC Networking component of Mozilla Firefox and Thunderbird. This vulnerability is classified as critical, with the root cause being CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer. An attacker could exploit this vulnerability to read from or write to a memory location outside the intended boundary of a buffer, leading to memory corruption. This impacts the confidentiality, integrity, and availability of the system. This vulnerability affects Firefox versions up to 149, Firefox ESR versions prior to 140.10, Thunderbird versions up to 149, and Thunderbird ESR versions prior to 140.10.(CVE-2026-6776)
