semver-minor and semver-patch version updates by adding both corresponding
update types, while leaving security updates unaffected.

You can use the ignore option in your dependabot.yml configuration file to prevent Dependabot from creating pull requests for specific dependencies or update types [1][2][3]. Key points regarding the configuration: - Configuration Location: You define these rules under the ignore key within your dependabot.yml file [1][4]. - Dependency Name: Use the dependency-name parameter to target specific packages [2][3]. You can use the wildcard character * to match zero or more characters (e.g., to ignore a range of related libraries) [4][5]. - Update Types: Use the update-types parameter to ignore specific semantic versioning levels [2][3]. Supported values include version-update:semver-patch, version-update:semver-minor, and version-update:semver-major [2][5]. - Security Updates Note: The update-types configuration only applies to version updates [1][2]. Security updates are exempt from these restrictions and will continue to be generated regardless of your update-types settings [1]. Example Configuration: To ignore all patch updates for a specific dependency, you can use the following syntax [1][3]: updates: - package-ecosystem: "npm" directory: "/" schedule: interval: "weekly" ignore: - dependency-name: "@types/node" update-types: ["version-update:semver-patch"] Additionally, you can use @dependabot ignore comment commands directly on existing pull requests to manage these preferences without modifying the configuration file [1][6]. If a dependency is matched by both an allow rule and an ignore rule, the ignore rule takes precedence [5][3].

Security Misconfiguration
Reachability: External
CWE: CWE-16
Scope the dtolnay/rust-toolchain ignore rule to version updates only. The dependency-specific rule currently ignores all update types. Add version-update:semver-minor and version-update:semver-patch. Dependabot will continue creating security updates, because update-types applies only to version updates.

Summary
Dependabot vulnerability alerts and security updates have also been enabled separately at the repository level, so security fixes are not dependent on the weekly version-update policy.
