Tenable has extracted the preceding description block directly from the CIQ security advisory.

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

The version of Firefox ESR installed on the remote Windows host is prior to 115.35. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2026-31 advisory.

  - Integer overflow in the Libraries component in NSS. This vulnerability was fixed in Firefox 148, Firefox     ESR 140.8, Thunderbird 148, and Thunderbird 140.8. (CVE-2026-2781)

  - Memory safety bugs present in Firefox ESR 115.34, Firefox ESR 140.9, Thunderbird ESR 140.9, Firefox 149     and Thunderbird 149. 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-2026-6785)

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