Primary sources: NVD · CVE.org · FIRST EPSS

Froxlor from 2.3.8 before 2.3.15 contains an information disclosure vulnerability that allows administrators with customers_see_all to view every account's API key and secret through an unscoped WHERE 1 query in api_keys.php. Attackers can read the super administrator's apikey and secret from the detail modal and replay them to the API to gain super administrator control.
