About GitHub-curated alert rules
The GitHub-curated alert rule, Dismiss low impact alerts, auto-dismisses certain types of vulnerabilities that are found in npm dependencies used in development. These alerts cover cases that feel like false alarms to most developers as the associated vulnerabilities:
- Are unlikely to be exploitable in a developer (non-production or runtime) environment.
- May relate to resource management, programming and logic, and information disclosure issues.
- At worst, have limited effects like slow builds or long-running tests.
- Are not indicative of issues in production.
Note: Automatic dismissal of low impact development alerts is currently only supported for npm.
The GitHub-curated Dismiss low impact alerts rule includes vulnerabilities relating to resource management, programming and logic, and information disclosure issues. For more information, see "Publicly disclosed CWEs used by the Dismiss low impact alerts rule."
Filtering out these low impact alerts allows you to focus on alerts that matter to you, without having to worry about missing potentially high-risk development-scoped alerts.
By default, GitHub-curated Dependabot alert rules are enabled on public repositories and disabled for private repositories. Administrators of private repositories can opt in by enabling alert rules for their repository.
Enabling the Dismiss low impact alerts rule for your private repository
You first need to enable Dependabot alerts for the repository. For more information, see "Configuring Dependabot alerts."
