Descriptions

The implementation of Brave Desktop's privacy-preserving analytics system (P3A) between 1.1 and 1.18.35 logged the timestamp of when the user last opened an incognito window, including Tor windows. The intended behavior was to log the timestamp for incognito windows excluding Tor windows. Note that if a user has P3A enabled, the timestamp is not sent to Brave's server, but rather a value from:Used in last 24hUsed in last week but not 24hUsed in last 28 days but not weekEver used but not in last 28 daysNever usedThe privacy risk is low because a local attacker with disk access cannot tell if the timestamp corresponds to a Tor window or a non-Tor incognito window.

La implementación del sistema de análisis de preservación de la privacidad de Brave Desktop (P3A) versiones entre 1.1 y 1.18.35, registró la marca de tiempo de la última vez que el usuario abrió una ventana de incógnito, incluyendo las ventanas Tor. El comportamiento previsto era registrar la marca de tiempo para las ventanas de incógnito, excluidas las ventanas Tor. Tome en cuenta que si un usuario tiene habilitado P3A, la marca de tiempo no se envía al servidor de Brave, sino un valor from:Used en las últimas 24hUsed en la última semana pero no 24hUsed en los últimos 28 días pero no usaba weekEver pero no en los últimos 28 daysNever usado. El riesgo de la privacidad es bajo porque un atacante local con acceso al disco no puede decir si la marca de tiempo corresponde a una ventana Tor o una ventana de incógnito que no es Tor
