{"id":"CVE-2026-86417","summary":"MISP Dashboard Template REST API Exposes Template Owner Email Addresses to Unauthorized Users","details":"Affected versions of MISP inconsistently enforced email-address visibility in DashboardsController::listTemplates().\n\n\nThe query always fetched User.email, while redaction happened only inside the non-REST rendering branch. As a result, the same authenticated user who saw redacted data in the normal HTML interface could request the REST/JSON representation and receive template owners’ email addresses without the intended privilege check.\n\n\nThe fix moves the decision to a centralized User::canSeeEmails() authorization helper. Email addresses are now fetched only when the requester is a site administrator or the instance explicitly enables Security.disclose_user_emails. The same helper is also reused by other dashboard widgets to keep email-disclosure policy consistent.\n\nVersion affected: ≤2.5.45","modified":"2026-09-09T03:47:23.520388183Z","published":"2026-09-07T12:17:43.320Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/86xxx/CVE-2026-86417.json","cna_assigner":"CIRCL","cwe_ids":["CWE-200","CWE-862"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/86xxx/CVE-2026-86417.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-86417"},{"type":"FIX","url":"https://github.com/MISP/MISP/commit/fd554c3bd.patch"},{"type":"PACKAGE","url":"https://github.com/MISP/MISP"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/misp/misp","events":[{"introduced":"0"},{"fixed":"fd554c3bd"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"last_affected":"2.5.45"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-86417.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
