Summary
matrix-hookshot is a Matrix bot for connecting to external services like GitHub, GitLab, JIRA, and more. When Hookshot 6 version 6.0.1 or below, or Hookshot 5 version 5.4.1 or below, is configured with GitHub support, it is vulnerable to a Denial of Service (DoS) whereby it can crash on restart due to a missing check. The impact is greater to you untrusted users can add their own GitHub organizations to Hookshot in order to connect their room to a repository. This vulnerability is fixed in 6.0.2 and 5.4.2.
