CVE-2026-94401Network attack vector

Authenticated file read and SSRF via XML import

Published Sep 21, 2026 · Updated Sep 21, 2026

File-handling flaws in MISP before 2.5.47 allow remote authenticated users with modify permission to read local files or trigger SSRF. The addMISPExportFile method passes uploaded content to Xml::build with file reading enabled, so a path or URL is treated as a locator rather than XML data. A valid account with modify permission can expose server files or send requests to internal services without further user interaction.
