Machine-written summary

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

Prefect (versions up to and including 3.6.18) is affected by an argument injection flaw in the GitHubRepository block of the prefect-github integration. An attacker who can control the reference field can inject arbitrary git command-line options, which can lead to server-side request forgery, credential theft, or remote code execution. No fixed version is listed.
