CVE-2023-6266
Published: April 11, 2026
Official Description
The Backup Migration plugin for WordPress is vulnerable to unauthorized access of data due to insufficient path and file validation on the BMI_BACKUP case of the handle_downloading function in all versions up to, and including, 1.3.6. This makes it possible for unauthenticated attackers to download back-up files which can contain sensitive information such as user passwords, PII, database credentials, and much more.
Technical Analysis
CVE-2023-6266 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2023-6266 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
