          "details": "This issue is confined to the Firefox ESR and Thunderbird client applications and requires end‑user interaction (opening crafted web or email content), so servers or VMs without these desktop applications are not exposed. Its CVSS profile reflects only low confidentiality and integrity impact with no availability impact, and there is no indication of active exploitation. Given typical enterprise VM/server deployments run headless workloads, this can be safely deprioritized relative to remotely exploitable server‑side issues.",
