Deeper analysis

CVE-2025-23819 is an Improper Limitation of a Pathname to a Restricted Directory vulnerability, classified under CWE-22, that enables Absolute Path Traversal in the WP Cloud plugin developed by Marco Milesi. This flaw affects the WP Cloud plugin in all versions from n/a through 1.4.3, as published on 2025-02-03.

The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating it can be exploited over the network by unauthenticated attackers with low attack complexity and no user interaction required. Successful exploitation allows attackers to achieve high confidentiality impact by traversing paths to access restricted files outside the intended directory.
