DevSpace through 6.3.21 fails to reject parent-directory segments in tar entry names from the in-pod sync stream. Attackers operating a malicious container can stream tar entries with traversal sequences to write arbitrary files on the developer workstation, enabling code execution.
Why it matters
- ▸ Remotely exploitable over the network — no physical or local access required
- ▸ Low attack complexity — no special conditions needed to exploit
- ▸ No authentication required
- ▸ Requires the victim to take an action (e.g. open a file or link)
Apply the vendor patch as soon as it's available or already released. User-awareness training reduces risk here, since exploitation depends on tricking a user into acting.
This analysis is generated from structured CVSS vector data, CISA KEV cross-referencing, and vendor/product category rules — not a manual expert review. Treat it as a starting point, not a substitute for your own assessment.
