The bug
With a certain setup, it is relatively easy to phase through a wall block and end up inside of it.
To reproduce (screenshots attached)
Create a new world in creative mode.
Open the creative menu, and grab a wall block, as well as any solid block.
Place two walls adjacent to each other.
Stand on the short side (doesn't matter which), right up against the wall.
Jump and place the solid block beneath you.
Walk backwards.
You are now inside of the wall block.
Expected behavior
You should not be able to put your player inside of a wall block, or phase through it in any manner.

Can be confirmed, i tested in 1.21.4 and 1.7.10 and the bug happen, this can be used to go under the wall, so it's a security risk for the niche domain of the "secured" locations with a roof made of walls without an edge of solid blocks.
More seriously, i think it's a minor bug, but still a bug, fixing it could be a good idea.
I think so too Luizima, I found the bug in my survival world while building an iron farm that used walls to prevent the iron golems from falling. Thankfully, there was a layer of solid blocks underneath, so I didn't fall to my death, but yes I do think this should be fixed
Thank you for your reply!
Yes, unfortunately, i'm not a moderator (yet), so i can't mark this as confirmed, this is my first day trying to help the Minecraft community on Mojira, i'm very shy irl, so i try to communicate more and more with the others, and i think helping others and communicating can be a good and original way to improve myself.
I hope this bug will be fixed, if you know any other people with a Mojira account, you can ask them to vote to make some visibility, and if you can, you can try to find other issues with walls and make a grouped report with all the issues you found (and that aren't already on your search result).
(Also, for the env, i don't think "Cyberpower PC w/ 12x AMD R5" is very useful, it's more the operating system and the Java version.)
Yes, thank you Luzimia, I also don't really like socializing irl, but Minecraft is one of my passions. I'm glad you took interest in this bug. and also yeah I didn't know what it wanted me to put for Environment lol
I appreciate the effort, but attaching screenshots of unrelated versions provides more noise than value. I've gone ahead and removed some screenshots which are not necessary. Knowing when a bug first appeared can be handy, but the 'in-between' versions are not so helpful. As long as it affects the latest version, it's relevant.
Additionally; instead of attaching 8 different screenshots, a video seems better suited. You can use programs like OBS.
