v3.11.3: 3.11.3 / 2026-04-27

Compare Source

This release fixes mutiple security issues.

We would like to thank the following people for the responsible disclosures:

  • Shadowbyte (4c1dr3aper) - Charlie Lewis for the Remote-Read snappy decode vulnerability.

  • Brett Gervasoni for the AzureAD OAuth client_secret vulnerability.

  • @​iiihaiii and @​Ngocnn97 for the Old UI XSS vulnerability.

  • [SECURITY] AzureAD remote write: Fix OAuth client_secret being exposed in plaintext via /-/config endpoint. GHSA-wg65-39gg-5wfj / CVE-2026-42151 #​18590

  • [SECURITY] Remote-read: Reject snappy-compressed requests whose declared decoded length exceeds the decode limit. GHSA-8rm2-7qqf-34qm / CVE-2026-42154 #​18584

  • [SECURITY] UI: Fix stored XSS via unescaped le label values in old UI heatmap chart tick labels. GHSA-fw8g-cg8f-9j28 #​18588

v3.11.2: 3.11.2 / 2026-04-13

Compare Source

This release has a fix for a Stored XSS vulnerability that can be triggered via crafted metric names and label values in Prometheus web UI tooltips and metrics explorer. Thanks to Duc Anh Nguyen from TinyxLab for reporting it.

  • [SECURITY] UI: Fix stored XSS via unescaped metric names and labels. CVE-2026-40179. #​18506
  • [ENHANCEMENT] Consul SD: Introduce health_filter field for Health API filtering. #​18499
  • [BUGFIX] Consul SD: Fix filter parameter being incorrectly applied to the Health API. #​18499

v3.11.1: 3.11.1 / 2026-04-07

Compare Source

  • [BUGFIX] Tracing: Fix startup failure for OTLP HTTP tracing with insecure: true. #​18469

v3.11.0: 3.11.0 / 2026-04-02

Compare Source

  • [CHANGE] Hetzner SD: The __meta_hetzner_datacenter label is deprecated for the role robot but kept for backward compatibility, use the __meta_hetzner_robot_datacenter label instead. For the role hcloud, the label is deprecated and will stop working after the 1 July 2026. #​17850
  • [CHANGE] Hetzner SD: The __meta_hetzner_hcloud_datacenter_location and __meta_hetzner_hcloud_datacenter_location_network_zone labels are deprecated, use the __meta_hetzner_hcloud_location and __meta_hetzner_hcloud_location_network_zone labels instead. #​17850
  • [CHANGE] Promtool: Redirect debug output to stderr to avoid interfering with stdout-based tool output. #​18346
  • [FEATURE] AWS SD: Add Elasticache Role. #​18099
  • [FEATURE] AWS SD: Add RDS Role. #​18206
  • [FEATURE] Azure SD: Add support for Azure Workload Identity authentication method. #​17207
  • [FEATURE] Discovery: Introduce prometheus_sd_last_update_timestamp_seconds metric to track the last time a service discovery update was sent to consumers. #​18194
  • [FEATURE] Kubernetes SD: Add support for node role selectors for pod roles. #​18006
  • [FEATURE] Kubernetes SD: Introduce pod-based labels for deployment, cronjob, and job controller names: __meta_kubernetes_pod_deployment_name, __meta_kubernetes_pod_cronjob_name and __meta_kubernetes_pod_job_name, respectively. #​17774

  • [FEATURE] TSDB: Add an experimental xor2-encoding feature flag for the new TSDB block float sample chunk encoding that is optimized for scraped data and allows encoding start timestamps. #​18062

  • [BUGFIX] AWS SD: Fix panic in EC2 SD when DescribeAvailabilityZones returns nil ZoneName or ZoneId. #​18133
  • [BUGFIX] Agent: Fix memory leak caused by duplicate SeriesRefs being loaded as active series. #​17538
  • [BUGFIX] Alerting: Fix alert state incorrectly resetting to pending when the FOR period is increased in the config file. #​18244

  • [BUGFIX] Rules: Fix alert state restoration when rule labels contain Go template expressions. #​18375
  • [BUGFIX] Scrape: Fix panic when parsing bare label names without an equal sign in brace-only metric notation. #​18229
  • [BUGFIX] TSDB: Fail early when use-uncached-io feature flag is set on unsupported environments. #​18219
  • [BUGFIX] TSDB: Fall back to CLI flag values when retention is removed from config file. #​18200
  • [BUGFIX] TSDB: Fix memory leaks in buffer pools by clearing reference fields before returning buffers to pools. #​17895

  • [BUGFIX] TSDB: Fix storage.tsdb.retention.time unit mismatch in file causing retention to be 1e6 times longer than configured. #​18200
  • [BUGFIX] Tracing: Fix missing traceID in query log when tracing is enabled, previously only spanID was emitted. #​18189
  • [BUGFIX] UI: Fix tooltip Y-offset drift when using multiple graph panels. #​18228
