Wolves edged 1-0 ahead in the first minute of added time at the end of the first half through Romain Saiss.
Brighton only partially cleared a corner from the right and Ruben Neves dinked the ball over their defence for Saiss to volley into the bottom left corner.
Enock Mwepu had Brighton's best two chances but the Zambia international twice fired over from close range when well placed.
Solly March also should have done better with a first half opportunity and there was disappointment for Yves Bissouma as he picked up his fifth booking of the season.
The defeat caps a tough week for Albion who have struggled with injuries and covid.

1. Rob Sanchez 7
Had no chance with the opening goal just before halftime. Looked far more assured with his distribution and some good saves. Better performance.
2. Tariq Lamptey 7
Lively figure down the right. Always willing to take on his marker and performed defensive duties well. Kept driving forward.
3. Joel Veltman 6
Was a doubt with an ankle injury but was solid and reliable as ever against a lively Traore.
4. Dan Burn 6
Captain for the evening and played in his preferred position on left side of the centre back. Booked for a foul on Traore.
