This vulnerability is discussed in a Stackexchange website:

https://unix.stackexchange.com/questions/333539/lxterminal-in-the-netstat-output/333578

The socket placed in /tmp is predictable and public-writable, Therefore
if Alice placed a file or lxterminal socket in
/tmp/.lxterminal-socket:0-bob, bob is unable to open lxterminal, or open
a lxterminal instance for Alice.

This bug is fixed in the commit:
https://git.lxde.org/gitweb/?p=lxde/lxterminal.git;a=commit;h=f99163c6ff8b2f57c5f37b1ce5d62cf7450d4648
