What is CVE-2026-73160?

The cti-transmute product developed by MISP has a Server-Side Request Forgery (SSRF) vulnerability that affects the /fetch_misp_event and /misp_search_events endpoints. This vulnerability occurs due to insufficient validation of supplied hostnames, allowing an attacker to leverage DNS records that point to internal addresses. As a result, unauthorized requests to sensitive internal resources can be made, potentially exposing private data. The recent patch has implemented stricter hostname resolution measures and access controls to mitigate this risk.
