CVE-2023-6360Public exploitNetwork attack vector

Database disclosure via failed date validation

Published Nov 30, 2023 · Updated Oct 10, 2024

SQL injection in My Calendar before 3.4.22 allows remote attackers to read the WordPress database through the public events REST route. my_calendar_rest_route passes the from and to values into my_calendar_get_events, where failed date parsing falls back to the current date and lets invalid input pass mc_checkdate before raw interpolation into SQL. The REST route is unauthenticated in 3.4 releases; versions before 3.4 are exposed only when the external API is enabled, which is not the default.
