Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

GHSA-qw5r-ppcg-f8rj affects the Go package github.com/StacklokLabs/mkp before version 0.4.1. A remote attacker who can reach the server on the network, without authentication, can send one crafted request that sets very large log size limits, causing the server to load the whole pod log into memory until it runs out and is terminated. Upgrade to version 0.4.1 or later. The source lists no other workaround.
