Allison, 23, has made nine first-class appearances across his career, scoring 265 runs, including three half-centuries, and taking 18 wickets at 28.27.
He has featured three times for Essex in the Championship in 2023, taking one wicket.
Worcestershire head coach Alan Richardson said: "He's a good fit for our bowling attack, and I'm sure he'll be a valuable asset to the team.
"Ben is a tall, right-arm bowler who bowls with pace and seam. He's also a good fielder and has a great attitude, and someone we believe can make a real impact as we look to achieve promotion."
"We wish Ben well during his time at Worcestershire, where he will receive some valuable first-class experience and hopefully finish his individual season on a high," added Essex head coach, Anthony McGrath.
"The move will also provide him with some valuable first-team cricket, which has been hard to come by so far this season due to the strength in depth we possess in our attack here."
