Description
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

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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/VictoriaMetrics/VictoriaMetrics. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update github.com/VictoriaMetrics/VictoriaMetrics to 1.146.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8q3c-rjr9-xxrp is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-8q3c-rjr9-xxrp is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-8q3c-rjr9-xxrp. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-8q3c-rjr9-xxrp in your dependencies?
O3 detects GHSA-8q3c-rjr9-xxrp across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
