Advisory Summary

CVE-2026-73160 is a HIGH security vulnerability vulnerability (CWE-918: Server-Side Request Forgery (SSRF)) affecting Software libraries in the Maven ecosystem. The weakness occurs when the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-73160

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-73160, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Affected versions of cti-transmute contain an SSRF vulnerability in the /fetch_misp_event and /misp_search_events endpoints. The URL validation routine checked whether a supplied hostname was itself an IP literal and rejected private, loopback, link-local, or reserved IPs. However, ordinary domain names were accepted without resolving them first. An attacker could therefore use a hostname whose DNS record pointed to an internal address and cause the cti-transmute server to issue requests into its internal network. The commit explicitly states that anonymous callers could make the server request the internal target and read the response. The fix resolves hostnames using socket.getaddrinfo(), checks that every resolved address is globally routable, and additionally places @login_required on both affected MISP fetch/search routes.
