Each vulnerability on this page lists the affected version range and the fixed version to move to. Open the vulnerability for the version you actually run — fixes are specific to a release line, not to the package as a whole.

How do I monitor github.com/prometheus/alertmanager for upcoming vulnerabilities?

Upload the manifest or SBOM for your application at vulert.com/scanner and Vulert keeps checking the github.com/prometheus/alertmanager version you actually run against new disclosures, then alerts you when one affects it. There is no installation and no source-code access required.
