The discussion revolves around a recent incident involving GitLab's Duo, where a remote prompt injection vulnerability led to the potential theft of source code. This situation highlights the risks associated with data leakage from untrusted third-party servers during AI application integrations. Users have expressed concerns about the failure of major vendors to adequately address such vulnerabilities before deployment. The mention of similar issues in GitHub Copilot Chat further emphasizes the prevalence of this problem. There are recommendations to avoid integrating large language models (LLMs) into critical platforms until prompt injection vulnerabilities are fully resolved. Moreover, concerns were raised about GitLab's decision to run Duo as a system user without adequate safeguards, indicating a lapse in security practices.
