Lights leak when using Adaptive Probe Volumes
How to reproduce:
1. Open the attached project “APV Leaks.zip“
2. Open the “OutdoorsScene“ Scene
3. Bake the Probe Volumes by pressing “Generate Lighting“ in the Lighting window (Window>Rendering>Lighting)
4. Observe the area of the “Cube“ GameObject beneath the “DynamicObjectStandin“ GameObject in the Scene view
Expected result: There are no lights coming from under the “Cube (1)“ GameObject
Actual result: Lights are coming from under the “Cube (1)“ GameObject
Reproducible with: 2022.2.15f1, 2023.1.0b11, 2023.2.0a10
Can’t test with: 2020.3.47f1 (APVs are not supported), 2021.3.22f1 (“Scene at Assets/OutdoorsScene.unity is loaded and has probe volumes, but not part of the same baking set as the active scene.“ error)
Reproduced on: macOS 13.0.1 (Intel), Windows 10 (by reporter)

Resolution Note:
This is indeed a limitation of the APV system. When leaking is too problematic and when increasing the wall size is not possible, I would then advise to increase APV resolution.
Instead of increasing the resolution globally you could use multiple Probe Volumes :
Add an additional subdivision level in the Baking Set setting, for example 0.33m between probes (1/3 of the actual level)
On your Global Probe Volume, override the subdivision level to exclude this new smaller level. It won't change your actual setup, your scene will use a minimum of 1m between probes.
Add some Local Probe Volumes in problematic areas and use this smaller 0.33m subdivision level, this way you can add resolution only where it's needed, like near this problematic wall
