Priority 95/100

Un critical flaw (CVE-2026-89026) nell'Issabel Framework permette l'esecuzione di comandi OS da parte di attaccanti non autenticati grazie a una chiave JWT hard-coded. L'exploit è attivo in rete da settembre 2026. Una patch è disponibile dal 1° agosto 2026.

Why it matters

Per le PMI italiane, questa vulnerabilità potrebbe portare a compromissioni di sistemi PBX, esecuzione di comandi OS e potenziale accesso a dati sensibili. La mancanza di patch potrebbe esporre le infrastrutture a attacchi mirati.

  • Maggiore controllo sugli accessi e sulle chiavi di firma
  • Rilevamento tempestivo di attività sospette
