31
FAUCET Score

CVE-2023-6971 describes a critical Remote File Inclusion vulnerability in the Backup Migration plugin for WordPress, affecting versions 1.0.8 to 1.3.9. This flaw allows unauthenticated attackers to execute arbitrary code on the server by manipulating the 'content-dir' HTTP header. Successful exploitation is contingent on the server's php.ini having 'allow_url_include' enabled, a setting that is deprecated and typically disabled by default. With a CVSS score of 9.8 (Critical), the vulnerability presents a high risk of complete compromise (confidentiality, integrity, availability). Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
