Prometheus Alertmanager vs Grype: at a glance
What is Prometheus Alertmanager?
Alertmanager 0.34.2 turns off CORS by default, breaking cross-origin API calls.
Alertmanager handles deduplication, grouping, silencing and routing of Prometheus alerts. 0.34.2 (October 29) stops sending CORS headers by default, so cross-origin calls to api/v2 now fail unless --web.cors.origin is set, and rebuilds with Go 1.26.10 to distrust the compromised eMudhra intermediates. 0.34.1 fixed inhibitions that could un-mute alerts, and 0.34.0 split auth and rate-limit failures out of the clientError metric reason.
What is Grype?
Grype widens distro accuracy while each release clears its own dependency advisories.
Grype's autumn releases stay on matching accuracy. v0.121.0 carries AlmaLinux fix dates onto replaced RHEL matches and finds GitHub Swift advisories it previously missed, v0.120.0 marks SLES as a comprehensive distro and stores NVD SSVC decision points, and v0.119.0 exposes distro-fixed dropped matches through --show-suppressed. Each minor also carries a large dependency sweep, with v0.121.0 remediating five golang.org/x/net advisories.

◆ Current state
Alertmanager handles deduplication, grouping, silencing and routing of Prometheus alerts. 0.34.2 (October 29) stops sending CORS headers by default, so cross-origin calls to api/v2 now fail unless --web.cors.origin is set, and rebuilds with Go 1.26.10 to distrust the compromised eMudhra intermediates. 0.34.1 fixed inhibitions that could un-mute alerts, and 0.34.0 split auth and rate-limit failures out of the clientError metric reason.
◆ Where it's heading
The 0.3x line keeps shipping breaking changes outside major versions: metric reason splits in 0.34.0, per-group markers in 0.33.0 and now a CORS default in a patch. Operators need to read every release note, not just minors.
◆ Prediction
Expect 0.35.0 to carry further breaking changes in the vein of 0.33 and 0.34, though the entries do not say what it will contain.
Grype
5.0INFRA · APIS
Grype widens distro accuracy while each release clears its own dependency advisories.
◆ Current state
Grype's autumn releases stay on matching accuracy. v0.121.0 carries AlmaLinux fix dates onto replaced RHEL matches and finds GitHub Swift advisories it previously missed, v0.120.0 marks SLES as a comprehensive distro and stores NVD SSVC decision points, and v0.119.0 exposes distro-fixed dropped matches through --show-suppressed. Each minor also carries a large dependency sweep, with v0.121.0 remediating five golang.org/x/net advisories.
◆ Where it's heading
Accuracy remains the roadmap, and the work is increasingly about distro-specific truth: fix dates, extended support and comprehensive coverage. SSVC data in the database is the one new kind of signal, since it adds decision guidance beyond severity. Reachability has still not moved past Go in these notes.
◆ Prediction
SSVC decision points are stored but not yet described as a user-facing output, so surfacing them in results is the natural next step. These notes give no signal on a second reachability ecosystem.
