Security readout for executives and security teams
Plain-English summary
CVE-2019-14286 is a stored cross-site scripting issue in MISP 2.4.111. A malicious event can trigger script execution when a user switches to the event-graph view. Business urgency depends on whether your MISP instance accepts untrusted events and who can view event graphs.
Executive priority
Prioritize remediation for MISP instances that ingest third-party events or support multiple analyst accounts. The issue is not evidenced as actively exploited, but stored XSS can affect trusted users and sensitive threat-intelligence workflows.
Technical view
The vulnerability is reported in app/webroot/js/event-graph.js in MISP 2.4.111. It is stored XSS requiring a crafted MISP event and user interaction with the event graph toggle. The supplied sources provide a fixing commit reference but no CVSS score, CWE, affected-version range, or named fixed release.
Likely exposure
Exposure is likely limited to organizations running MISP 2.4.111 or nearby vulnerable code and processing crafted or untrusted MISP events. Internet exposure alone is not enough; exploitation requires malicious event content and a user viewing the event graph.
Exploitation context
The source bundle does not show KEV listing or active exploitation. The CVE text states a malicious MISP event must be crafted and the event-graph view toggled to trigger the issue. No exploit maturity or public abuse evidence is provided.
Researcher notes
Evidence is narrow: one CVE description and a GitHub commit reference. The affected range, CVSS, CWE, and fixed release are not supplied. Avoid assuming broader MISP impact without confirming code lineage against the referenced change.
Mitigation direction
- Check MISP guidance and release notes for the fixed version containing commit 26bedd8a.
- Upgrade affected MISP 2.4.111 deployments to a vendor-supported fixed release.
- Limit event creation and import rights to trusted users until patched.
- Treat externally supplied MISP events as higher risk until remediation is confirmed.
Validation and detection
- Inventory MISP deployments and flag version 2.4.111 for review.
- Confirm whether app/webroot/js/event-graph.js includes the referenced fix commit.
- Review whether untrusted users or feeds can create events viewed by analysts.
- Check whether analysts commonly use the event-graph view on imported events.
