Gravity is a manipulation of space-time geometry where more massive objects creates more curvature and vice versa. Now, speaking quite loosely that yes,light affected by gravity. One of the simple proof of it that is the gravitational lensing. Now more advanced and modern theory suggests that when (inside a black hole) the space time curvature are so high ,light goes only inward direction . No outward possible paths are allowed from inside a black hole.
Now,if we speak of gravitons,a quanta of gravitational force, is not interacted with electromagnetic waves(light or visible light). Actually,inside a black hole,the escape velocity of black hole is far more than that of the speed of light. So, it's not about only for the light but also for every objects (since light speed is the maximum),
