The Vikinger theme for WordPress (CVE-2025-2238) contains a privilege escalation vulnerability affecting all versions up to and including 1.9.30. The vulnerability was discovered and disclosed on April 24, 2025. The issue stems from insufficient usermeta restrictions in the 'vikingerusermetaupdate_ajax' function (NVD, Wordfence).
The vulnerability is classified as CWE-269 (Improper Privilege Management) with a CVSS v3.1 base score of 8.8 (HIGH), and vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. The issue exists in the usermeta update functionality, specifically within the 'vikingerusermetaupdate_ajax' function, which fails to properly restrict user permissions (NVD).
The vulnerability allows authenticated attackers with Subscriber-level access or higher to escalate their privileges to Administrator-level, potentially gaining full control over the WordPress installation (NVD).
Users of the Vikinger theme should upgrade to a version newer than 1.9.30 when available. Until then, site administrators should carefully monitor user activities and consider restricting user registration if possible (Themeforest).
