- CVE-2026-75889: arbitrary file reads due to the `prometheus.operator.servicemonitors` component allowing users who can modify `ServiceMonitor` resources in a watched namespace to specify an arbitrary local file through `bearerTokenFile` (bsc#1277429).
- CVE-2026-81521: go.mongodb.org/mongo-driver: MongoDB Go Driver: Write redirection via unvalidated database name in Client.BulkWrite (bsc#1278693).

Changes for alloy:

- Update to version 1.19.2.
- Update to version 1.19.1.
- Update to version 1.19.0:
* BREAKING CHANGE: prometheus.operator.servicemonitors now rejects endpoints that reference local files by default. Set allow_arbitrary_file_access = true to preserve previous behavior.
* prometheus.enrich: Support multi-label matching
* prometheus.relabel: Add opt-in TTL cache mode
* telemetry: Add new metrics for graph connections and pyroscope forwarded entries
* database_observability: Exclude system schemas from MySQL health checks and redact query text in explain_plans
- Update to version 1.18.1:
* Add nop receiver to OTel Engine
