Source Advisory Statement

### Impact The eventing-github cluster-local server doesn't set `ReadHeaderTimeout`‬‭ which could lead do a DDoS‬ ‭attack, where a large group of users send requests to the server causing the server to hang‬ ‭for long enough to deny it from being available to other users, also know as a Slowloris‬ ‭attack. ### Patches Fix in `v1.12.1` and `v1.11.3` ### Credits The vulnerability was reported by Ada Logics during an ongoing security audit of Knative involving Ada Logics, the Knative maintainers, OSTIF and CNCF.
