XSS in Membership Database Project Membership Database ≤ 1.0
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-0514 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Membership Database Project Membership Database. Its CVSS base score is 6.1 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 43% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.
Validates web inputs to reject script-related content that could produce XSS.
Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly target introduction of XSS via coding standards/testing (mostly), yet the single broad outcome leaves many specific neutralization vectors unaddressed (partial).
Patching and EOL replacement can remediate known XSS instances in libraries or frameworks (partial) but do nothing to enforce input neutralization in application code (none).
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
A.5.6 only promotes membership in groups to improve knowledge, receive alerts, and share information; it performs no action that stops XSS exploitation (or even the underlying neutralization defect) and is a pure dependency for other controls per the owner's labeling rule.
