Threat Score
Mozilla released Firefox 137 addressing three high-severity CVEs — a use-after-free in XSLTProcessor (CVE-2025-3028) and multiple memory-safety bugs (CVE-2025-3030, CVE-2025-3034) affecting Firefox, Firefox ESR, and Thunderbird; these flaws could enable memory corruption and arbitrary code execution, and users are strongly urged to update to the patched versions immediately.
