Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 41.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

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

Deeper analysis

CVE-2025-67617 is a Deserialization of Untrusted Data vulnerability (CWE-502) in the Consult Aid WordPress theme developed by themeton, enabling Object Injection. This issue affects all versions of the Consult Aid theme from its initial release through version 1.4.3.

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), making it exploitable over the network by unauthenticated attackers requiring low complexity and no user interaction. Attackers can achieve high impacts on confidentiality, integrity, and availability, potentially leading to severe outcomes such as arbitrary code execution through injected PHP objects.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Directly remediates the deserialization flaw in the Consult Aid WordPress theme versions through <=1.4.3, preventing object injection exploitation as advised by Patchstack.

SI-10 Information Input Validation good match
prevent

Enforces validation of untrusted data inputs to block malicious deserialization payloads that enable PHP object injection in the vulnerable theme.

SI-9 Information Input Restrictions partial match
prevent

Restricts input types, formats, and volumes at system boundaries to mitigate acceptance of crafted data triggering the deserialization vulnerability.
