Description

OpenLIT is an open source platform for AI engineering. Prior to version 1.37.1, several GitHub Actions workflows in OpenLIT's GitHub repository use the `pull_request_target` event while checking out and executing untrusted code from forked pull requests. These workflows run with the security context of the base repository, including a write-privileged `GITHUB_TOKEN` and numerous sensitive secrets (API keys, database/vector store tokens, and a Google Cloud service account key). Version 1.37.1 contains a fix.

Affected products

openlit: from 1.36.2 before 1.37.1 — fixed in 1.37.1

How to fix

Upgrade to a fixed version: openlit 1.37.1. Check the vendor advisory for mitigations.
