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.","published":"2026-10-19T09:17:08.000Z","lastModified":"2026-10-19T19:17:26.000Z","status":"Deferred","sourceIdentifier":"5a6e4751-2f3f-4070-9419-94fb35b644e8","cvss":{"version":"4.0","score":5.3,"severity":"MEDIUM","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-200"],"affected":[],"epss":{"score":0.00309,"percentile":0.23514,"date":"2026-10-26","history":[{"date":"2026-10-19","score":0.00309,"percentile":0.22281}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.31%).
