The icon field of a galaxy object was persisted without any server-side validation through the galaxy add, edit, and sync/import capture endpoints. The stored value was subsequently concatenated directly into HTML markup by the D3-based correlation graph rendering scripts (both the default and Overmind themes) using the .html() method.\n\nA user holding the perm_galaxy_editor permission, which is granted to the stock User role, could store arbitrary HTML or JavaScript in the icon field. Any other user who opened the correlation graph of an event containing a cluster belonging to that galaxy would have the injected script executed in their browser session.\n\nImpact:\n\n- Arbitrary script execution in the context of the victim's MISP session\n\n- Potential theft of session credentials, manipulation of displayed data, or initiation of actions on behalf of the victim\n\n- Affects both the default and Overmind UI themes\n\nAffected versions: <2.5.48","state":0,"publishedAt":"2026-09-30T14:25:59.23+00:00","modifiedAt":"2026-09-30T15:28:06.728+00:00","affected":[{"ecosystem":"Vendor product","name":"MISP","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"cpes\": [\n                        \"cpe:2.3:a:misp:misp:*:*:*:*:*:*:*:*\"\n                    ],\n                    \"modules\": [\n                        \"Galaxy model\",\n                        \"Correlation Graph (default theme)\",\n                        \"Correlation Graph (Overmind theme)\",\n                        \"Galaxy sync/import capture\"\n                    ],\n                    \"product\": \"MISP\",\n                    \"programFiles\": [\n                        \"app/Model/Galaxy.php\",\n                        \"app/Lib/Tools/CorrelationGraphTool.php\",\n                        \"app/webroot/js/correlation-graph.js\",\n                        \"app/webroot/js/correlation-graphOvermind.js\"\n                    ],\n                    \"repo\": \"https://github.com/MISP/MISP\",\n                    \"vendor\": \"MISP\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"2.5.48\",\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N","score":6.2,"severity":"MEDIUM"}],"references":["https://github.com/MISP/MISP/commit/8ea5783dd"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-103389","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-103389","identifiers":["CVE-2026-103389"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
