The filtering of non-exportable tags was applied only once after the iteration over all reports, rather than to each individual report.\n\nAs a result:\n\n- All reports except the last one in the set were pushed to the remote MISP instance with their non-exportable tags intact, effectively disclosing restricted tag information to the receiving instance.\n\n- When the last report in the set was withheld (empty), a null report was pushed, causing the remote instance to fail saving the event.\n\nThis issue affects any MISP instance configured to push events with multiple reports to a remote server via synchronization.\n\nAffected: <2.5.48.","state":0,"publishedAt":"2026-10-19T08:53:57.689+00:00","modifiedAt":"2026-10-19T18:32:29.985+00:00","affected":[{"ecosystem":"Vendor product","name":"MISP","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"cpes\": [\n                        \"cpe:2.3:a:misp:misp:*:*:*:*:*:*:*:*\"\n                    ],\n                    \"modules\": [\n                        \"Event Synchronization\"\n                    ],\n                    \"product\": \"MISP\",\n                    \"programFiles\": [\n                        \"app/Model/Event.php\"\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:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/MISP/MISP/commit/0be4564a9"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-112179","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-112179","identifiers":["CVE-2026-112179"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
