CVE-2026-121436: Froxlor information disclosure in API keys listing

CVE-2026-121436 · Severity: high · CVSS 7.2 · Published 2026-11-03

Froxlor is a web hosting control panel that administrators use to manage customers and servers. A flaw in the API keys page allows reseller-level administrators to view every account's API credentials, including the super administrator's, by opening the detail modal. An attacker can then replay the stolen super administrator credentials to the API to gain complete control of the entire hosting panel.

Technologies: Froxlor. Vendors: Froxlor.

Technical details

An unscoped WHERE 1 query in api_keys.php allows any administrator with the customers_see_all flag to retrieve API keys for all users across all administrators when browsing the admin area, due to a missing owner predicate in one of three conditional branches. The detail modal then renders the full plaintext apikey and secret in the HTML response without truncation or authorization checks. The API authentication layer trusts a bare key and secret match without validating ownership, allowing the disclosed super administrator credentials to be replayed directly for authentication.
