CVE-2026-113677 · Severity: medium · CVSS 5.4 · Published 2026-10-20

Froxlor is a web hosting control panel that manages domains, subdomains, and associated infrastructure. An authenticated customer can exploit a missing authorization check in the SubDomains.delete API command to delete main domains assigned to them by resellers, orphaning vhosts, DNS records, and subdomains while artificially lowering the customer's subdomain quota to gain extra allocations.

## How to fix

- Fixed in 2.3.15

## Technical details

The SubDomains.delete API endpoint fails to verify ownership restrictions when a customer attempts to delete a main domain (parentdomainid=0) rather than a subdomain. An authenticated customer can bypass the web UI restriction by directly calling the API with a main domain ID, deleting domains owned by resellers and corrupting quota tracking by driving subdomains_used negative. The fix enforces a check to prevent non-admin users from deleting resources with parentdomainid=0.
