The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 128.10. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-32 advisory.

  - A process isolation vulnerability in Thunderbird stemmed from improper handling of javascript: URIs, which     could allow content to execute in the top-level document's process instead of the intended frame,     potentially enabling a sandbox escape. (CVE-2025-4083)

  - Thunderbird's update mechanism allowed a medium-integrity user process to interfere with the SYSTEM-level     updater by manipulating the file-locking behavior. By injecting code into the user-privileged process, an     attacker could bypass intended access controls, allowing SYSTEM-level file operations on paths controlled     by a non-privileged user and enabling privilege escalation. (CVE-2025-2817)

  - Modification of specific WebGL shader attributes could trigger an out-of-bounds read, which, when chained     with other vulnerabilities, could be used to escalate privileges. This bug only affects Thunderbird for     macOS. Other versions of Thunderbird are unaffected. (CVE-2025-4082)

  - Due to insufficient escaping of the special characters in the copy as cURL feature, an attacker could     trick a user into using this command, potentially leading to local code execution on the user's system.
    This bug only affects Firefox for Windows. Other versions of Firefox are unaffected. (CVE-2025-4084)

  - A vulnerability was identified in Thunderbird where XPath parsing could trigger undefined behavior due to     missing null checks during attribute access. This could lead to out-of-bounds read access and potentially,     memory corruption. (CVE-2025-4087)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
