JHipster release v6.3.0 Permalink to "JHipster release v6.3.0"

This release fixes an important security vulnerability:

  • Please read the security advisory here.
  • Are you vulnerable? if you use JWT, session or UAA authentication, and more importantly if you use our system to send a link to reset passwords, then you are affected. The algorithm used isn’t cryptographically secure, which means that an attacker could guess a reset link, and hence take over any account in the system.
  • How to fix the issue you probably don’t need to upgrade JHipster, as this just affects a few generated files, so this can be done manually. The issue is in the generated RandomUtil class. Here is this class in our sample application generated with JHipster v6.2.0 and here is the updated version, using JHipster v6.3.0. So all you need to do is copy the new file, which uses SecureRandom, and replace the older file.
  • How this issue was handled This issue was found by Jonathan Leitschuh, and was fixed in the next couple of hours by Frederik Hahne. Please note that we gave a $500 bug bounty to Jonathan as well as a $300 bug bounty to Frederik. For obvious security reasons, only the JHipster core dev team knew about this issue during that period. We then waited one day in order to inform everyone, including doing an advisory on our Twitter account so that our users are not caught up with a surprise emergency release.
  • What will happen next This is the first time we used the “security advisory” feature from GitHub. We certainly learned a lot, and we will provide in the very near future a clear path to report security advisories to the team.
