CVE-2026-1987 describes an Insecure Direct Object Reference vulnerability in the Scheduler Widget plugin for WordPress, affecting all versions up to 0.1.6. This flaw allows authenticated users, even those with Subscriber-level access, to modify any event within the scheduler by manipulating the 'id' parameter due to insufficient authorization and ownership checks in the 'scheduler_widget_ajax_save_event()' function. With a CVSS score of 5.4 (Medium), the vulnerability has a low attack complexity and can lead to unauthorized modification of event data. There is currently no evidence of active exploitation, nor are there publicly available exploit modules in Metasploit, Nuclei, or ExploitDB, and it has garnered minimal community discussion or media coverage.
