Summary

PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.51, the Jobs API create_app function mounts /api/v1/runs without authentication. Any reachable caller can submit jobs, read results, cancel runs, or delete jobs using operator credentials. The fix adds PRAISONAI_JOBS_API_KEY middleware for Authorization or X-API-Key. This issue is fixed in version 4.6.58.
