"The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 148.0. It is, therefore, affected
by multiple vulnerabilities as referenced in the mfsa2026-16 advisory.

  - Memory safety bugs present in Firefox 147 and Thunderbird 147. 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-2026-2807)

  - Sandbox escape due to incorrect boundary conditions in the DOM: Core & HTML component. This vulnerability
    affects Firefox < 148, Firefox ESR < 115.33, Firefox ESR < 140.8, Thunderbird < 148, and Thunderbird <
    140.8. (CVE-2026-2778)

  - Incorrect boundary conditions in the WebRTC: Audio/Video component. This vulnerability affects Firefox <
    148, Firefox ESR < 115.33, Firefox ESR < 140.8, Thunderbird < 148, and Thunderbird < 140.8.
    (CVE-2026-2757)

  - Use-after-free in the JavaScript: GC component. This vulnerability affects Firefox < 148, Firefox ESR <
    115.33, Firefox ESR < 140.8, Thunderbird < 148, and Thunderbird < 140.8. (CVE-2026-2758)

  - Incorrect boundary conditions in the Graphics: ImageLib component. This vulnerability affects Firefox <
    148, Firefox ESR < 115.33, Firefox ESR < 140.8, Thunderbird < 148, and Thunderbird < 140.8.
