Deeper analysis
The Membership Database WordPress plugin through version 1.0 is affected by a reflected cross-site scripting vulnerability (CWE-79) tracked as CVE-2023-0514. The flaw stems from insufficient sanitization and escaping of an unspecified parameter that is later reflected back into the page output, as indicated by its CVSS 3.1 score of 6.1.
An unauthenticated remote attacker can exploit the issue by crafting a malicious link that, when clicked by a high-privilege user such as an administrator, executes arbitrary script code in the victim's browser context with changed scope. The attack requires user interaction but needs no prior authentication.
The primary public reference is a WPScan advisory entry that documents the vulnerability; no specific patch version, mitigation steps, or workaround details are provided in the available information. The associated EPSS score remains flat at 0.1245 with no material increase since disclosure.
