Deeper analysis

CVE-2025-26976 is an Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability, classified under CWE-89, in the PrivateContent WordPress plugin developed by Aldo Latino. The issue affects PrivateContent versions from n/a through 8.11.4 inclusive. Published on 2025-03-15, it carries a CVSS v3.1 base score of 8.5 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:L), indicating high severity due to its network accessibility and potential for significant data exposure.

Low-privileged remote attackers, such as authenticated WordPress users (PR:L), can exploit the vulnerability over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Exploitation enables a scoped impact (S:C), achieving high confidentiality loss (C:H), such as unauthorized access to sensitive database contents, alongside low availability disruption (A:L) and no integrity impact (I:N).
