Title

VictoriaMetrics vmrestore: path traversal via crafted backup part names escapes restore root

Summary

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.

GHSA-8Q3C-RJR9-XXRP

Vulnerability from github – Published: 2026-09-03 17:49 – Updated: 2026-09-03 17:49

Summary

VictoriaMetrics vmrestore: Path traversal via crafted backup part names escapes restore root

Details

Summary

The VictoriaMetrics vmrestore utility does not validate backup part path components before writing restored files to the local filesystem. An attacker who can provide or modify a backup source can craft object names containing .. path components that cause vmrestore to write files outside the intended -storageDataPath restore root, subject to the permissions of the vmrestore process.

Impact

An attacker who can supply or modify the backup source -- for example by writing malicious object names to a compromised or misconfigured storage bucket -- can cause arbitrary files to be created or overwritten on the host running vmrestore, within the limits of the process's filesystem permissions.

Patches

Versions 1.146.0, 1.136.12, 1.122.25

Resources

https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.146.0
https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.136.12
https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.122.25

Note

VictoriaMetrics' security model assumes backup sources are trusted and access-controlled. This vulnerability requires an attacker to have write access to the backup storage (e.g. S3, GCS, or Azure Blob Storage bucket) used as the -src for vmrestore. Under a correctly secured deployment where backup storage access is properly restricted, unauthorized exploitation of this issue should not be possible. Users are advised to follow the principle of least privilege when granting access to backup storage buckets.

Severity

6.8 (Medium)

  "details": "### Summary\nThe VictoriaMetrics `vmrestore` utility does not validate backup part path components before writing restored files to the local filesystem. An attacker who can provide or modify a backup source can craft object names containing `..` path components that cause vmrestore to write files outside the intended `-storageDataPath` restore root, subject to the permissions of the `vmrestore` process.\n\n### Impact\nAn attacker who can supply or modify the backup source -- for example by writing malicious object names to a compromised or misconfigured storage bucket -- can cause arbitrary files to be created or overwritten on the host running `vmrestore`, within the limits of the process\u0027s filesystem permissions.\n\n### Patches\nVersions 1.146.0, 1.136.12, 1.122.25\n\n### Resources\n  - https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.146.0\n  - https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.136.12\n  - https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.122.25\n\n### Note\nVictoriaMetrics\u0027 security model assumes backup sources are trusted and access-controlled. This vulnerability requires an attacker to have write access to the backup storage (e.g. S3, GCS, or Azure Blob Storage bucket) used as the `-src` for `vmrestore`. Under a correctly secured deployment where backup storage access is properly restricted, unauthorized exploitation of this issue should not be possible. Users are advised to follow the principle of least privilege when granting access to backup storage buckets.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
