What an attacker can do

The source says the sysinfo REST endpoint compares the provided key to the stored opt-in key using a loose comparison, allowing unauthenticated attackers to send a boolean value and obtain the full system report whenever "Yes, automatically share my system information with The Events Calendar support team" setting is enabled. Vendor/CNA’s CVSS 3.1 assessment (base score 5.3/10) rates confidentiality impact as low; integrity and availability impact as none.
