No EPSS data is available, and the vulnerability is not listed in CISA\u2019s KEV catalog, implying no publicly known exploits. The attack vector requires authentication and web application interaction; a user must possess create_events or run_events rights to inject unsafe content, and an authenticated victim must later view a job detail for the payload to execute. Because the data is stored and rendered by the server, the risk is confined to the internal network or users with web UI access."}}}}, "created": "2026-04-08T19:34:20.848749+00:00", "updated": "2026-04-08T19:45:49.783424+00:00", "vendors": ["jhuckaby", "jhuckaby$PRODUCT$cronicle"]}
