Reporting Issues

Accumulo uses GitHub issues to track bugs and new features. Visit How to contribute for more information.

Reporting Security Issues (CVE)

We strongly encourage reporting potential security issues by privately emailing or That means, for example, that you should not create a public GitHub issue, since those would make the issue public. GitHub pull requests and any messages associated with any commits should not make any reference to the security nature of the commit.

The Accumulo project follows the standard ASF vulnerability handling process as outlined by the ASF Security Team.

An overview of the process is:

  • The reporter reports the vulnerability privately to Accumulo community by sending an email to or the ASF Security Team
  • The Accumulo project works privately with the reporter to resolve the vulnerability.
  • The Accumulo project creates a new release of the package the vulnerability affects to deliver its fix.
  • The Accumulo project publicly announces the vulnerability and describes how to apply the fix.


  1. Do not make information about the vulnerability public until it is formally announced by the Accumulo community.
  2. Do not email the user, dev mailing or any public mailing list
  3. Do not send a message via Slack
  4. Do not create a GitHub issue
  5. Do not create a GitHub pull request that makes any reference to the security nature of the commit.
