An EPSS score of less than 1% suggests that active exploitation is unlikely currently, and the vulnerability is not cataloged in the CISA Known Exploited Vulnerabilities list, further reducing urgency. Exploitation requires authenticated access as a Subscriber or higher; the attacker can then supply a target calendar ID and gain unauthorized access to that calendar\u2019s data. The combination of internal authentication and lack of ownership validation makes this attack straightforward for anyone with legitimate site credentials."}}}}, "created": "2026-04-28T04:00:05.165819+00:00", "updated": "2026-04-28T20:30:06.188480+00:00", "vendors": ["codepeople", "codepeople$PRODUCT$booking_calendar_contact_form", "wordpress", "wordpress$PRODUCT$wordpress"]}
