Description

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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pocketmine/pocketmine-mp, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update pocketmine/pocketmine-mp to 4.0.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-j5qg-w9jg-3wg3 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
