On April 15, 2026, Tails released version 7.6.2 as an emergency update to address a significant security vulnerability in the Tor Browser's confinement. This vulnerability could potentially be exploited by an attacker who has already gained control over the Tor Browser through another exploit. Users of Tails 7.0 or later are urged to perform automatic upgrades to mitigate this risk. If automatic upgrades fail or if Tails does not start post-upgrade, users are advised to conduct a manual upgrade. It is important to note that installing Tails instead of upgrading will result in the loss of Persistent Storage on the USB stick. The release emphasizes the necessity of upgrading to protect against potential exploitation. For detailed upgrade instructions, users can refer to the Tails website. The vulnerability underscores the ongoing need for vigilance in maintaining updated security measures.
