Denial Of Service (DoS)

PocketMine-MP is vulnerable to Denial Of Service DoS. The vulnerability is due to improper validation because the server does not verify uniqueness of packIds in STATUSSENDPACKS, allowing a malicious Bedrock client to send duplicate UUIDs and force repeated pack transfers until memory is exhauste...

GHSA-G274-C6JJ-H78P PocketMine-MP allows malicious client data to waste server resources due to lack of limits for explode()

Impact Due to lack of limits by default in the explode function, malicious clients were able to abuse some packets to waste server CPU and memory. This is similar to a previous security issue published in https://github.com/pmmp/PocketMine-MP/security/advisories/GHSA-gj94-v4p9-w672, but with a...

Denial Of Service (DOS)

pocketmine/raklib is vulnerable to Denial Of Service DOS. The vulnerability is caused by a missing validation on an upper bound for the maximum number of messages/packets that can be stored inside reliable-ordered queue until the data in the queue is ordered. A malicious client can exploit above...
