Deeper analysis

CVE-2025-67997 is a Deserialization of Untrusted Data vulnerability (CWE-502) in the BoldThemes Travelicious WordPress theme, enabling PHP object injection. The issue affects all versions of Travelicious from n/a through those prior to 1.6.7. Published on 2026-02-20, it 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 critical severity due to its potential for severe impacts across confidentiality, integrity, and availability.

Remote attackers require no privileges, authentication, or user interaction to exploit this vulnerability over the network with low complexity. Successful exploitation allows object injection, which can lead to arbitrary code execution, data manipulation, or system compromise on affected WordPress sites running vulnerable Travelicious theme versions.

Patchstack advisories recommend updating the Travelicious theme to version 1.6.7 or later, where the vulnerability is addressed. Security practitioners should verify theme versions on WordPress sites and apply updates promptly, especially for internet-facing installations.
