{"schema":"threatline.record/2","record":{"id":"CVE-2026-112179","aliases":[],"summary":"MISP Event Synchronization Exposes Non-Exportable Tags on Remote Instances","details":"In MISP, the event synchronization process contained a logic error in the preparation of event reports for remote push. 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.","categories":["Unclassified"],"product":"MISP","vendor":"MISP","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-112179","source_modified_at":"2026-10-19T18:32:29.985Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"MISP","vendor":"MISP","versions":[{"lessThan":"2.5.48","status":"affected","version":"0","versionType":"semver"}],"defaultStatus":null}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-112179","source_modified_at":"2026-10-19T18:32:29.985Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"MISP","ecosystem":null},"version":"2.5.48","basis":"first unaffected version stated in the CVE record"}],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00309,"percentile":0.22524,"score_date":"2026-10-23"},"published_at":"2026-10-19T08:53:57.689Z","modified_at":"2026-10-19T18:32:29.985Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-112179","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T18:32:29.985Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-112179","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/MISP/MISP/commit/0be4564a9","tags":["patch"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-19T18:32:17.990508Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-19T18:32:29.985Z","content_hash":"9f7725469a0ac247071358bdd77b1c67366285ce7498292eb091f206fa313248"}}
