This high-severity CVE scores 8.7 under NVD CVSS v3. EPSS exploit probability: 0.9% (58th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

jsuites is an open source collection of common required javascript web components. In affected versions users are subject to cross site scripting (XSS) attacks via clipboard content. jsuites is vulnerable to DOM based XSS if the user can be tricked into copying _anything_ from a malicious and pasting it into the html editor. This is because a part of the clipboard content is directly written to innerHTML allowing for javascript injection and thus XSS. Users are advised to update to version 4.9.11 to resolve.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

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.
