Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability was found in ahujasid blender-mcp up to 7636d13bded82eca58eb93c3f4cd8708dfdfbe8b. The affected element is the function requests.get of the file src/blender_mcp/server.py of the component ZIP File Handler. The manipulation of the argument zip_file_url results in server-side request forgery. The attack can be executed remotely. The exploit has been made public and could be used. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. The patch is identified as 5b37be25242e73dc4cf1328974d30458b9e5d67e. It is advisable to implement a patch to correct this issue.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-918

The server can be induced to make requests to a URL an attacker controls, turning it into a proxy into internal networks and cloud metadata services. It's especially dangerous behind a trusted network boundary. The fix is strict allow-listing of destinations and blocking access to internal address ranges.

Recommended fix High confidence

Update to commit 5b37be25242e73dc4cf1328974d30458b9e5d67e or later on the main branch (blender-mcp uses rolling release)

  1. Clone or navigate to the blender-mcp repository
  2. Verify the current HEAD is at or before the vulnerable commit 7636d13bded82eca58eb93c3f4cd8708dfdfbe8b
  3. Fetch the latest changes from the remote repository
  4. Checkout or pull the fix commit 5b37be25242e73dc4cf1328974d30458b9e5d67e (or the latest main/master branch which should include this fix)
  5. Review PR #205 at https://github.com/ahujasid/blender-mcp/pull/205 to understand the fix applied to src/blender_mcp/server.py in the ZIP File Handler
  6. Ensure proper validation or sanitization is in place for the zip_file_url parameter to prevent SSRF
  7. Rebuild/deploy the application with the patched code
