Aribo, 27, who recently returned from the 2023 African Cup of Nations with Nigeria, came off the bench to make a significant impact.
Initially starting as a substitute, the Nigerian entered the game with Southampton and Birmingham City deadlocked at 3-3.
Stepping in for William Smallbone, the former Charlton Athletics player emerged as the hero in added time, seizing an opportunity from a corner kick and guiding the ball into the net with his left foot.
This marked Aribo’s second goal for Southampton since his return from international duty.
With a total of three goals in 24 league appearances this season, the former Glasgow Rangers’ star continues to be a key contributor to Southampton’s success.
The victory not only showcased Aribo’s prowess but also bolstered Southampton’s promotion bid.
The club currently holds the fourth position in the table, amassing 70 points from 35 games, as they strive for promotion in the ongoing season.
