Deeper analysis

CVE-2025-60066 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, affecting the Katelyn WordPress theme developed by axiomthemes. The issue impacts all versions of Katelyn up to and including 1.0.10, as documented under CWE-98. Published on 2025-12-18, 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).

Unauthenticated remote attackers (PR:N) can exploit this vulnerability over the network (AV:N) with high attack complexity (AC:H) and without requiring user interaction (UI:N). Successful exploitation allows attackers to achieve high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), potentially enabling local file inclusion to read sensitive files, execute arbitrary code, or disrupt system operations on affected WordPress sites running the vulnerable theme.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

SI-10 requires validating inputs from external sources like HTTP parameters used in PHP include/require statements, directly preventing malicious filename manipulation leading to local file inclusion.

SI-2 Flaw Remediation good match
preventrecover

SI-2 mandates identifying, reporting, and correcting flaws such as this PHP file inclusion vulnerability through timely patching of the affected Katelyn theme.

CM-6 Configuration Settings partial match
prevent

CM-6 enforces secure configuration settings for PHP components, such as open_basedir restrictions or disabling allow_url_include, to limit the scope of local file inclusion exploits.
