Prometheus 3.13.3: security patches + TSDB data-integrity bugfixes

Mon, 14 Sep 2026 17:40:51 +0000

Platform/SRE — Plan: Two Go library security fixes (compress, x/crypto) plus serious TSDB bugs — deleted series causing missing samples after restart and out-of-order queries blocking compaction for hours causing memory growth — make this a priority upgrade for any team on Prometheus 3.13.x; no KEV listing or hard deadline, but schedule 3.13.3 upgrade this sprint.
CI/CD — Skip
Leader — Skip
Signals: deprecation mentioned (no explicit date found)
