CVE-2026-17541: Bit File Manager authorization bypass in REST API logs endpoint

CVE-2026-17541 · Severity: high · CVSS 7.5 · Published 2026-08-10

The Bit File Manager WordPress plugin before version 6.9.1 contains a flaw in its REST API that allows unauthenticated visitors to access a file activity log endpoint without any permission checks. An attacker can retrieve the complete history of file operations performed on the website, including file paths, timestamps, and the names of staff members who performed each action. This information disclosure could aid attackers in reconnaissance or social engineering campaigns against the site's operators.

Technical details

The vulnerability is an authorization bypass (CWE-200) in a REST API route that exposes the file activity log. The `/wp-json/file-manager/v1/logs/all` endpoint fails to verify user authentication or capabilities before returning activity log entries. An unauthenticated attacker can send a POST request with attacker-controlled pagination parameters (pageNo, limit) to retrieve the entire activity log without authentication headers, nonces, or cookies. The response includes file operation details, absolute server paths, user IDs, display names, and timestamps. The flaw affects installations that have run version 6.8.8 or earlier (which created the activity-log table) and have since been upgraded; fresh installs on 6.8.9+ are unaffected as the table is never created due to a separate installer bug. The issue is fixed in version 6.9.1.
