Deeper analysis

CVE-2026-39487 is an Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability that enables Blind SQL Injection in the Amelia WordPress plugin (ameliabooking). This flaw affects Amelia versions from n/a through 2.1.1 and is classified under CWE-89.

The vulnerability carries a CVSS v3.1 base score of 7.6 (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:L). High-privileged users (PR:H) can exploit it over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Exploitation results in high confidentiality impact (C:H), allowing unauthorized data access, low availability impact (A:L), and a changed scope (S:C) with no integrity impact (I:N).
