As reported by PC Gamer , the leak includes nearly 90 games, including
Control Resonant , Kingdom Hearts 4 , Gears of War E-Day , Tomb Raider:
Legacy of Atlantis , and Persona 6 . The leaked achievements are listed for each title on Exophase, including spoilers for major plot points, character reveals, and even weapon unlocks (notably for Kingdom Hearts 4 ), despite missing full descriptions. It's effectively created a minefield of spoilers
to avoid, which is made worse since the list includes games that don't even have a release date. Latest Videos From TechRadar Watch full video here:

It's not exactly clear how this leak occurred on Valve's end, but it doesn't appear to be a breach of the Steam platform. Instead, it may very well be an issue with Valve's API exposure, at least according to Exophase owner Mike Bendel, who claims it's a "possible screw-up on Valve's end", which makes
this the second slip-up in just a few weeks.

Recently, around 12TB to 13TB of early prototypes, unreleased titles, and scrapped builds of games between 2003 and 2013 were leaked from Steam, including games such as GTA 5 , The Binding of Isaac , and even some of Valve's very own games like Left 4 Dead .

There's clearly a major security issue at hand with Steam, and until it's addressed, game leaks seem inevitable.
