The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2025-60237 is a Deserialization of Untrusted Data vulnerability (CWE-502) in the Themeton Finag WordPress theme, which allows object injection. This issue affects the Finag theme from unknown initial versions through version 1.5.0 inclusive.

The vulnerability carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating that unauthenticated attackers can exploit it remotely over the network with low attack complexity and without requiring user interaction. Successful exploitation enables high-impact effects on confidentiality, integrity, and availability through malicious object deserialization.

The primary advisory reference is available from Patchstack at https://patchstack.com/database/Wordpress/Theme/finag/vulnerability/wordpress-finag-theme-1-5-0-php-object-injection-vulnerability?_s_id=cve, which documents the PHP object injection flaw in Finag theme version 1.5.0. Security practitioners should review this source for detailed mitigation recommendations, including potential patches or workarounds.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Directly mandates timely remediation and patching of the deserialization flaw in Finag theme versions through <=1.5.0 to eliminate object injection vulnerability.

SI-10 Information Input Validation good match
prevent

Requires validation and sanitization of untrusted inputs to prevent malicious serialized data from being deserialized into exploitable objects.

SI-9 Information Input Restrictions partial match
prevent

Restricts system inputs to authorized values, blocking receipt of untrusted serialized data targeted at the deserialization vulnerability.
