Deeper analysis

CVE-2026-22433 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified as a PHP Remote File Inclusion issue that enables PHP Local File Inclusion, affecting the CloudMe WordPress theme developed by AncoraThemes. The vulnerability impacts CloudMe versions from n/a through 1.2.2 and is associated with CWE-98. It was published on 2026-03-05 with a CVSS v3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).

Remote attackers can exploit this vulnerability over the network without requiring privileges or user interaction, though it demands high attack complexity. Successful exploitation grants high-impact access to confidentiality, integrity, and availability, allowing attackers to include and potentially execute local files on the server, which could lead to sensitive data exposure or system compromise.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly requires validation of untrusted filename inputs in PHP include/require statements to block local file inclusion exploits in the CloudMe theme.

SI-2 Flaw Remediation good match
prevent

Mandates timely identification, prioritization, and patching of the specific PHP file inclusion flaw affecting CloudMe versions through 1.2.2.

CM-6 Configuration Settings partial match
prevent

Enforces secure PHP configuration settings such as open_basedir restrictions and disabling allow_url_include to limit exploitable file paths for LFI attacks.
