# Chaos V-Ray: unauthenticated package upload lets attackers run remote code

Link for people: https://infrastack.ai/live/CVE-2026-104989 (this .md is for agents)

Chaos Software V-Ray versions through 2.0.19 have an uncontrolled search path in the package upload feature. A remote attacker without an account can redirect library loading and execute arbitrary code.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed V-Ray version against the affected range (through `2.0.19`)
- Look for the package upload feature being reachable from the network

## Timeline

- 2026-11-09T17:27:37+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-104989
- 2026-11-09T17:29:13+00:00 analyst — Could not reach a primary source: web-cli search out of Exa credits, NVD page via WebFetch returned no content, chaos.com/security 404. No vendor advisory, fixed version or default-on status found. Nothing verified; fix stays unknown. Needs vendor advisory from Chaos to settle fix and whether package upload is on by default.

## From the sources

Uncontrolled search path element in package upload feature in Chaos Software V-Ray versions through 2.0.19 allows remote unauthenticated attackers to execute arbitrary code via redirecting access to libraries
