Patched version
Not yet available
GHSA-36P7-VC44-83PF

An early warning has been issued for a code injection vulnerability in ChromaDB Python package versions 0.4.17 and later. Users of these versions are advised to assess their exposure and take immediate action.

What happened

An early warning has been issued regarding a code injection vulnerability in the ChromaDB Python package. This vulnerability, tracked as GHSA-36P7-VC44-83PF, affects versions 0.4.17 and later. It allows an authenticated attacker with UPDATE_COLLECTION permission to run arbitrary code on the server by sending a malicious model repository with trust_remote_code set to true to a specific API endpoint.

The vulnerability was first flagged on June 12, 2026. It is currently under investigation, and no exploitation in the wild has been confirmed. Users of affected versions should review their configurations and permissions to assess their exposure to this vulnerability.

What to do about it

How 0Day would have caught this

MATCHED TO YOUR ACTUAL DEPENDENCY GRAPH0Day matches every incoming threat signal against your GitHub organization’s full dependency graph, including transitive dependencies. If chromadb is anywhere in your dependency tree, the engineers who own the affected repositories get a push alert the moment it is flagged — no manual audit to remember to run.

Read how this differs from waiting on a scanner to catch a known advisory, or see the exact, read-only access 0Day needs to do this for an organization.

Frequently asked questions

Am I affected?
