Google Chrome receives a major safety replace because the tech big addresses a serious safety vulnerability within the browser. Particularly, the Chrome flaw uncovered customers’ looking historical past to web sites, together with any malicious hyperlinks arrange by menace actors.
Google Chrome Flaw Uncovered Looking Historical past
Reportedly, a sneaky safety problem rigged Chrome browser for a number of years, probably risking customers’ privateness. The flaw existed in Google Chrome for over 20 years, exposing customers’ looking historical past.
Explaining the matter in a submit, Google’s Engineer Kyra Seevers described how the tech big addressed this previous problem with Chrome 136.
Particularly, it’s a standard phenomenon to see the colour of beforehand visited hyperlinks modified from blue to purple. This obvious UI change was achieved utilizing the CSS :visited selector. As soon as a person visits a hyperlink, it seems purple throughout all different web sites displaying that hyperlink, sharing the beforehand visited standing of the previous hyperlink to the newly visited website.
Whereas it appears a innocent design function for customers’ comfort, this customizability additionally makes it straightforward for the menace actors to trace customers’ looking historical past and exercise.

Any beforehand visited web sites would seem purple there, even when the person didn’t click on these hyperlinks when visiting the malicious website.
Google Deployed Hyperlink Partitioning As A Repair
This publicity of beforehand visited hyperlink logs grew to become attainable as a consequence of an absence of segregation for beforehand visited and new web sites. To handle this vulnerability, Google has applied :visited hyperlink partitioning with the newest Chrome launch. This partitioning prevents :visited styling on visited URLs throughout unrelated web sites. As a substitute, it will solely seem on websites looking which the person clicked on a selected hyperlink to go to.
This element will, nevertheless, stay seen to the web site even when the person visited a hyperlink prior to now. Nonetheless, it is not going to expose such looking actions to web sites that the person doesn’t use for visiting one other hyperlink, even when it consists of these hyperlinks.
Summarizing this phenomenon within the submit, Seevers said,
Partitioning refers to storing your hyperlinks with extra details about the place they had been clicked. In Chrome, that is: hyperlink URL, top-level website, and body origin. With partitioning enabled, your
:visitedhistorical past is not a worldwide checklist that any website can question. As a substitute, your:visitedhistorical past is “partitioned” or separated by the context the place you visited that hyperlink from within the first place.
Moreover, the sub-pages of a web site (self-links), even when the person doesn’t click on on them in a selected context, will even stay seen as :visited to a web site.
A website can show its personal subpages as
:visited, even when these hyperlinks weren’t clicked on this context earlier than. As a result of websites produce other strategies of monitoring whether or not a person has visited its subpages, no new info is given to those websites with the introduction of self-links.
Customers can expertise this variation beginning with Google Chrome 136. Nonetheless, for curious customers, Google permits enabling this function through chrome://flags by typing “#partition-visited-link-database-with-self-links” within the search bar.
