Overview
CVE-2026-94401 is a known-severity vulnerability. It was published on September 21, 2026.
Technical description
MISP has a file-handling vulnerability that could let certain authenticated users make the server read files or access internal network services.
When importing an XML file, MISP did not properly verify that the uploaded content was actually XML. Because of this, a user with permission to modify data could upload a file containing a local file path or a web address instead.
If a local file path was supplied, MISP could read that file from the server. If a URL was supplied, MISP could make a request to that address, including systems that may only be reachable from inside the organization’s network.
The vulnerability could therefore expose sensitive local files and allow unauthorized requests to internal services.
Exploitation required a valid MISP account with modify permissions, but no additional user interaction was needed.
Version affected: <2.5.47

How can CyberStrike help with CVE-2026-94401?
CyberStrike is an open-source, AI-augmented pentesting engine.
