Script execution via unescaped directory content
Published Jul 2, 2026 · Updated Jul 2, 2026
Stored XSS in QuantumCloud Simple Link Directory 15.0.5 and earlier allows remote attackers to inject scripts into directory pages. The affected rendering path places attacker-controlled content into pages without adequate sanitization or output escaping, but the handler and parameter are undisclosed. No authentication is required, but a user must view an injected page; the script then runs in that user's browser context with that session's privileges.
