Deeper analysis

CVE-2026-25413 is an Unrestricted Upload of File with Dangerous Type vulnerability (CWE-434) in the WPBookit Pro WordPress plugin (wpbookit-pro) developed by iqonicdesign. The issue enables the use of malicious files through arbitrary file uploads and affects all versions of the plugin from n/a through 1.6.18 inclusive. Published on 2026-03-25, it carries a CVSS v3.1 base score of 9.9, reflecting its critical severity.

The vulnerability can be exploited remotely (AV:N) with low attack complexity (AC:L) by an authenticated attacker with low privileges (PR:L), requiring no user interaction (UI:N). Exploitation changes scope (S:C) and results in high impacts to confidentiality, integrity, and availability (C:H/I:H/A:H), potentially allowing full server compromise via uploaded malicious files such as webshells.
