Deeper analysis

CVE-2026-22367 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 AncoraThemes Coworking WordPress theme. This issue affects Coworking versions from n/a through 1.6.1. It carries 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) and maps to CWE-98.

The vulnerability can be exploited by unauthenticated attackers with network access, requiring high attack complexity and no user interaction. Successful exploitation allows high-impact compromises to confidentiality, integrity, and availability, such as including and potentially executing arbitrary local PHP files on the server.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Directly requires timely identification, reporting, and patching of the PHP Local File Inclusion flaw in Coworking theme versions through 1.6.1 to eliminate the vulnerability.

SI-10 Information Input Validation good match
prevent

Enforces validation of filenames and paths in PHP include/require statements to block attacker-controlled inputs enabling arbitrary local file inclusion.

CM-6 Configuration Settings partial match
prevent

Mandates secure configuration settings for PHP, such as open_basedir restrictions or disabling dangerous functions, to limit the scope and impact of file inclusion exploits.
