GHSA-66jq-2c23-2xh5
No affected components available
Impact
Affected versions are vulnerable to DoS attacks because the snappy decoder ignored VictoriaMetrics request size limits allowing malformed blocks to trigger excessive memory use. This could lead to OOM errors and service instability. The fix enforces block-size checks based on MaxRequest limits.
