What is CVE-2026-58268?

The SIPGO library, used for creating SIP services in the Go programming language, is susceptible to a denial of service vulnerability. Prior to version 1.4.1, the library's ParserStream.parseSingle function was flawed due to improper handling of the Content-Length header. An unauthenticated attacker could exploit this by sending a stream message with an oversized declared length, triggering excessive memory allocation. This could lead to service disruptions before the SIP body is processed, affecting availability for legitimate users. The vulnerability has been addressed in the 1.4.1 release.

Affected Version(s)
