Type:
security
Severity:
Low
Release date:
2026-06-03 09:22:41 UTC
Description:
- CVE-2026-33378: fix denial of service (OOM) from a non-positive fill interval reaching the SQL fill/resample loop, which then stepped backwards in time and never terminated, allocating rows until the server ran out of memory. Reject interval <= 0 in the $__timeGroup / $__unixEpochGroup macros of the PostgreSQL, MySQL and MSSQL datasources, and additionally guard the shared resample call site (qm.Interval > 0) so a negative fillInterval supplied directly in the query JSON cannot reach the loop either
CVEs fixed:
