LLM-synthesized narrative grounded in this CVE's description and references.
Unauthenticated sensitive data exposure in Backup Migration plugin <=2.1.1 allows attackers to view restricted information.
Vulnerability
The Backup Migration plugin for WordPress (also known as backup-backup) versions up to and including 2.1.1 contain an unauthenticated sensitive data exposure vulnerability. This allows attackers to access sensitive information without any authentication, due to missing authorization checks on certain endpoints. [1]
Exploitation
An attacker can exploit this vulnerability remotely without requiring any authentication or user interaction. By sending a crafted HTTP request to the vulnerable endpoint, the attacker can retrieve sensitive data that would normally be restricted to authorized users only. [1]
Impact
Successful exploitation leads to the exposure of sensitive information, potentially including database credentials, backup files, and other configuration data. This can be used to further compromise the WordPress site and escalate attacks. [1]
Mitigation
The vulnerability is fixed in version 2.1.2 of the Backup Migration plugin. Users are strongly advised to update to this version or later immediately. No workaround is available. Enabling auto-updates for the plugin can help ensure timely patching. [1]
