Last modified

CVE-2026-66004 is a medium-severity vulnerability rated 6/10 on the CVSS scale. BlenderMCP before commit 30a3308 contains a path traversal vulnerability in the download_polyhaven_asset method that allows attackers to write arbitrary files by injecting traversal sequences in API response include keys. Attackers performing MITM attacks or prompt injection can supply malicious paths like '../../.bashrc' to overwrite sensitive files and achieve persistent code execution.. EPSS estimates a 0.29% chance of exploitation in the next 30 days.
