Description Adam Mariš 2018-02-27 12:00:43 UTC 
The class handling unauthenticated Mercurial post-commit hook notification requests at the /mercurial/ path unnecessarily extended another type that handled requests to the .../search/ sub-path.

This allowed submission of search queries to Jenkins, and getting a list of search results usually available to anyone with Overall/Read permission. In current Jenkins releases, those are typically the names of known users (both actual users of Jenkins, and known SCM committers) and nodes (master and agents).
