CVE-2025-68274Public exploitNetwork attack vector

Unauthenticated application crash via missing To header

Published Dec 16, 2025 · Updated Dec 16, 2025

Starting with 0.3.0, nil pointer dereference in emiago SIPGO before 1.0.0-alpha-1 allows remote attackers to crash SIP applications. The sip/response.go NewResponseFromRequest function dereferences res.To() and accesses its Params map after parsing accepts a request that omits the To header. Network access to an SIP application that uses this function is sufficient; one unauthenticated malformed request terminates the application process.
