CVE-2026-113677 — Froxlor 0.10.0 before 2.3.15 Missing Authorization via SubDomains.delete API

Froxlor from 0.10.0 before 2.3.15 contains a missing authorization vulnerability in the SubDomains.delete API command that allows authenticated customers to delete reseller-provisioned main domains by supplying a main domain id. Attackers can bypass the web UI restriction to remove domains, orphan vhost, DNS and subdomain records, and drive subdomains_used below zero to gain extra subdomain allowance.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • Technical severity (medium)+3
  • CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Froxlor Froxlor).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.
