An attacker who can induce a site administrator to visit a crafted URL containing a malicious tag name parameter can execute arbitrary JavaScript in the administrator's browser session.\n\nPreconditions:\n\n- The target must be running a MISP instance with the legacy taxonomy tag confirmation views enabled.\n\n- The victim must be an authenticated site administrator.\n\n- The victim must navigate to the attacker-crafted URL (e.g., via a phishing link).\n\nSecurity impact:\n\n- Execution of arbitrary client-side script in the context of the administrator's browser.\n\n- Potential theft of session tokens, CSRF tokens, or other sensitive data accessible from the page.\n\n- Potential for performing privileged actions on behalf of the administrator within the MISP interface.\n\nAffected versions: <2.5.48.","state":0,"publishedAt":"2026-10-01T08:48:38.222+00:00","modifiedAt":"2026-10-01T15:07:17.448+00:00","affected":[{"ecosystem":"Vendor product","name":"MISP","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"cpes\": [\n                        \"cpe:2.3:a:misp:misp:*:*:*:*:*:*:*:*\"\n                    ],\n                    \"modules\": [\n                        \"Taxonomies (add_tag\",\n                        \"disable_tag views)\"\n                    ],\n                    \"product\": \"MISP\",\n                    \"programFiles\": [\n                        \"app/View/Taxonomies/add_tag.ctp\",\n                        \"app/View/Taxonomies/disable_tag.ctp\"\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:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":5.1,"severity":"MEDIUM"}],"references":["https://github.com/MISP/MISP/commit/9619083c8"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-103662","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-103662","identifiers":["CVE-2026-103662"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
