Unauthenticated Denial of Service in the octokit/webhooks library
Impact
Versions v9.26.0, v10.9.x), v11.1.x, v12.0.x all contained the code that would throw the error.
Specifically, during a pentest we encountered a bug in the octokit/webhooks library (a dependency of Probot, a framework for building Github Apps). The resulting request was found to cause an uncaught exception that ends the nodejs process.
The problem is caused by an issue with error handling in the @octokit/webhooks library because the error can be undefined in some cases.
Credit goes to @pb82 (for the early analysis) and @rh-tguittet (for discovery).
