Indian Govt Issues Critical Security Warning for Mozilla Firefox, Thunderbird Users

  • The Indian government's CERT-In has issued a high-severity security warning for Mozilla Firefox and Thunderbird users.
  • Multiple vulnerabilities in Mozilla products, including Firefox versions prior to 147.0.2 and Thunderbird versions prior to 140.7.1 and 147.0.1, have been identified.
  • These vulnerabilities could allow remote attackers to exploit systems, bypass privacy anti-tracking, and exfiltrate content from partially encrypted emails.
  • Exploitation could occur if users open specially crafted web requests, posing a risk of data theft.
  • Users are strongly advised to update their Mozilla products to the latest versions immediately to patch these security flaws and avoid installing apps from untrusted sources.
