Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 0.9% 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.
CVE-2023-4547 is a cross-site scripting vulnerability rated problematic in SPA-Cart eCommerce CMS version 1.9.0.3. The issue resides in the /search endpoint where unsanitized input to the filter[brandid] and filter[price] parameters allows script injection, corresponding to CWE-79. It carries a CVSS 3.1 score of 3.5 reflecting network attack vector, low complexity, and the requirement for an authenticated user to trigger the flaw via a reflected or stored vector.
An authenticated attacker can supply malicious payloads through the affected filter parameters in a crafted search request. Successful exploitation results in execution of attacker-controlled script in the context of a victim user's browser session, enabling actions such as theft of session tokens or manipulation of page content displayed to that user.
The EPSS score for this CVE rose from a low baseline to a peak of 0.1641 on 2025-12-11 before receding to the current value of 0.0993, indicating a period of increased exploitation interest after public disclosure. Public references consist of technical reports on VulDB and a Packet Storm entry reproducing the issue, with no vendor patch or mitigation guidance supplied in the available sources.

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.
Validates web inputs to reject script-related content that could produce XSS.
Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.
Directly prevents execution of attacker-supplied code written into data memory regions.
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).
PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

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.
