Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

VictoriaMetrics vmrestore, in the Go module github.com/VictoriaMetrics/VictoriaMetrics before 1.122.25, from 1.123.0 before 1.136.12, and from 1.137.0 before 1.146.0, does not validate path components in backup part names. An attacker who can write to the backup source bucket can use crafted names with ".." components to create or overwrite files outside the restore directory, limited by the vmrestore process's permissions. Upgrade to 1.122.25, 1.136.12, or 1.146.0 depending on your release line.
