CVE-2026-61625

23th percentile - higher than 23% of all known CVEs

VictoriaMetrics is a scalable solution for monitoring and managing time series data. Prior to 1.122.25, 1.136.12, and 1.146.0, vmrestore does not validate backup part path components before using lib/backup/actions/restore.go and lib/backup/fslocal/fslocal.go to write restored data below storageDataPath. An attacker who can supply or modify an S3, GCS, Azure Blob Storage, or other backup source can place .. components in object names. When an operator restores that source, the crafted names can create or overwrite files outside the intended restore root within the filesystem permissions of the vmrestore process. This issue is fixed in versions 1.122.25, 1.136.12, and 1.146.0.

The risk includes overwriting or creating files outside the intended directory, potentially leading to system compromise, privilege escalation, or execution of malicious code. The attack requires the ability to modify the backup source, which may be possible remotely.

It is recommended to immediately upgrade to one of the fixed versions (1.122.25, 1.136.12, or 1.146.0). Also, verify the integrity of backup sources and restrict access to them.
