Deeper analysis

CVE-2026-27995 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified as PHP Remote File Inclusion but enabling PHP Local File Inclusion, in the ThemeREX Justitia WordPress theme. This issue affects Justitia versions from n/a through 1.1.0.

The vulnerability has 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), indicating exploitation is possible over the network by unauthenticated attackers with no user interaction required, though it demands high attack complexity. Successful exploitation allows attackers to achieve high impacts on confidentiality, integrity, and availability, potentially enabling arbitrary file reads or local file inclusion leading to further compromise.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Information input validation directly mitigates improper filename control in PHP include/require statements by validating user-supplied inputs to prevent local file inclusion.

SI-2 Flaw Remediation good match
prevent

Flaw remediation requires timely identification, reporting, and correction of the specific LFI vulnerability in the Justitia WordPress theme.

SI-9 Information Input Restrictions good match
prevent

Information input restrictions at system boundaries block malicious file paths or traversal sequences exploited in the PHP LFI vulnerability.
