Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Versions of openlit from 1.36.2 up to but not including 1.37.1 are affected, due to GitHub Actions workflows in the project's repository that run untrusted code from forked pull requests with base-repository privileges. An attacker who can open a pull request from a fork could run code with a write-privileged token and access to sensitive repository secrets, such as API keys and a Google Cloud service account key. Upgrade openlit to version 1.37.1 or later.
