GHSA-j5qg-w9jg-3wg3low3.3

Inability to de-op players if listed in ops.txt with non-lowercase letters

The advisory, in context

Impact

Originally reported in iTXTech/Genisys#1188

PotterHarry98
potterharry98

deop PotterHarry98

will remove potterharry98 from the ops.txt but not PotterHarry98.

Operator permissions are checked using Config->exists() with lowercase=true, which will result in a match: https://github.com/pmmp/PocketMine-MP/blob/22bb1ce8e03dba57173debf0415390511d68e045/src/utils/Config.php#L449

This means that it's possible to make yourself impossible to de-op (using commands) by adding your name to ops.txt with uppercase letters.

Patches

Workarounds

This can be easily addressed by removing the offending lines from ops.txt manually.
