What happened

Researchers Ian Carroll and Sam Curry reported that McDonald's AI-powered hiring tool, McHire (using Paradox.ai's "Olivia" chatbot), could purportedly be accessed via default admin credentials and an insecure direct object reference in an internal API. The flaws allegedly allowed viewing of applicants' personally identifiable information and chat histories. McDonald's and Paradox reportedly patched the issues within a day of disclosure; Paradox stated only five records were accessed.
