This document describes the management of vulnerabilities for the Mercurius project and all modules within the Mercurius organization.

Individuals who find potential vulnerabilities in Mercurius are invited to report them via GitHub at https://github.com/mercurius-js/mercurius-subscription-client/security or via email at matteo.collina@gmail.com.

Avoid creating new "informative" reports. Only create new report a potential vulnerability if you are absolutely sure this should be tagged as an actual vulnerability. Be careful on the maintainers time.

When a potential vulnerability is reported, the following actions are taken:

Delay: 5 business days

Within 5 business days, a member of the security team provides a first answer to the individual who submitted the potential vulnerability. The possible responses can be:

• Acceptance: what was reported is considered as a new vulnerability
• Rejection: what was reported is not considered as a new vulnerability
• Need more information: the security team needs more information in order to evaluate what was reported.

Triaging should include updating issue fields:

• Asset - set/create the module affected by the report
• Severity - TBD, currently left empty

Delay: 90 days

When a vulnerability is confirmed, a member of the security team volunteers to follow up on this report.

With the help of the individual who reported the vulnerability, they contact the maintainers of the vulnerable package to make them aware of the vulnerability. The maintainers can be invited as participants to the reported issue.

With the package maintainer, they define a release date for the publication of the vulnerability. Ideally, this release date should not happen before the package has been patched.

The report's vulnerable versions upper limit should be set to:

• * if there is no fixed version available by the time of publishing the report.
• the last vulnerable version. For example: <=1.2.3 if a fix exists in 1.2.4

Delay: 90 days

Within 90 days after the triage date, the vulnerability must be made public.

Severity: Vulnerability severity is assessed using CVSS v.3.

If the package maintainer is actively developing a patch, an additional delay can be added with the approval of the security team and the individual who reported the vulnerability.

At this point, a CVE will be requested by the team.
