Description
ESPHome through 2026.7.0-dev discloses plaintext passwords via its web_server component. In WebServer::text_json_ (esphome/components/web_server/web_server.cpp), a text entity configured with mode: password (TEXT_MODE_PASSWORD) has its JSON "state" field correctly masked as "********", but the same serialization path unconditionally writes the raw password into the JSON "value" field via set_json_icon_state_value/set_json_value.
