No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

money-pos 1.0 contains a stored Cross-Site Scripting (XSS) vulnerability. When processing returns, the backend fails to filter or escape the goodsName parameter, directly concatenating it into the order log description; the frontend subsequently renders this content using v-html. An attacker with product creation privileges can inject a malicious JavaScript payload, causing unauthorized code execution when an administrator views the order logs.

No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
