CVE-2026-48868

Vulnerability

The Simple Shopping Cart plugin for WordPress (versions 5.2.9 and earlier) contains an unauthenticated Insecure Direct Object Reference (IDOR) vulnerability. This flaw allows a remote attacker to bypass authorization and access controls, potentially exposing sensitive files, folders, or enabling direct database interaction. No authentication is required to exploit this issue [1].

Exploitation

An attacker with network access to a WordPress site running the vulnerable plugin can exploit this IDOR by manipulating object references (e.g., parameters such as IDs) in requests. No prior authentication or user interaction is needed. The attack does not require any special privileges, making it exploitable in mass-exploit campaigns targeting thousands of websites simultaneously [1].

Impact

Successful exploitation leads to unauthorized access to sensitive data (information disclosure), including files, folders, or database contents. The attacker gains read access to resources they should not be able to reach, potentially compromising site confidentiality. The CVSS v3 base score is 7.5 (High), reflecting the lack of authentication and ease of exploitation [1].

Mitigation

The vulnerability is fixed in version 5.3.0 of the Simple Shopping Cart plugin. Users should immediately update to this version or later. If updating is not possible, site owners should consult their hosting provider or web developer for assistance. No virtual patch is available for this specific vulnerability. The plugin is considered likely to be exploited, so prompt action is advised [1].
