MISP Arbitrary Local File Read and SSRF via MISP Export Upload
CVSS 4.0 8.3 HIGHCheck source for fixed versionsKEV status unknown
cve-program · CVE-2026-94401
PublishedMISP 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

Exploitation and risk
Source statusCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
Which CVEs have scores here?
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.
Risk history
Compare earlier KEV listings and daily EPSS scores. Advisory wording and affected versions have a separate history.
When does an EPSS score appear as a change?
A prediction change is reported when EPSS rises from below 10% to 10% or higher. Other daily score changes remain in this history.
Advisory history
1 saved versionsSee how the publisher's advisory changed over time. Each link opens the version saved at that time. The publisher's update date can differ from the date shown here.
How advisory history works
Each link identifies one complete publisher record. History can include advisories that previously shared an identifier; an identifier removed by a publisher no longer establishes a current relationship. A historical link shows only that record and earlier saved versions. Failed checks and unchanged reads do not create new versions.
