Insufficient escaping in the “Copy as cURL” feature could have been used to trick a user into executing unexpected code on Windows. This did not affect the application when running on other operating systems. This vulnerability affects Firefox < 144, Firefox ESR < 140.4, Thunderbird < 144, and Thunderbird < 140.4.

The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 140.4. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-85 advisory.

  - Memory safety bugs present in Firefox ESR 140.3, Thunderbird ESR 140.3, Firefox 143 and Thunderbird 143.
    Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of     these could have been exploited to run arbitrary code. (CVE-2025-11715)

  - A compromised web process using malicious IPC messages could have caused the privileged browser process to     reveal blocks of its memory to the compromised process. (CVE-2025-11710)

  - Use-after-free in MediaTrackGraphImpl::GetInstance() (CVE-2025-11708)

  - A compromised web process was able to trigger out of bounds reads and writes in a more privileged process     using manipulated WebGL textures. (CVE-2025-11709)

  - There was a way to change the value of JavaScript Object properties that were supposed to be non-     writeable. (CVE-2025-11711)

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