Authorization Flaw in efw4.X (CVE-2026-44260)
Summary
Vulnerability in efw4.X (CVE-2026-44260). Confidential information can be exposed externally. Mitigation: upgrade to 4.08.010 or later.
Original description
The description as published by the source.
efw4.X is an Enterprise Framework for Web. Prior to 4.08.010, the readonly flag set on the JSP tag is intended to prevent file modifications. When protected=true, elfinder_checkRisk enforces that the client sends readonly=true (matching the session value), but no event handler checks the readonly value before performing write operations. The flag only controls client-side UI elements (disabling buttons) and response metadata (write: 0, locked: 1). An attacker who sends requests directly (bypassing the UI) can perform all file operations despite readonly=true. This vulnerability is fixed in 4.08.010.
