  • Sep 22, 2026SIPGO is a library for writing SIP services in the GO language.CVE-2026-77322 · Other software · emiago · reported by GitHubHigh 7.5

    SIPGO is a library for writing SIP services in the GO language. Prior to 1.4.3, WSConnection.Read in sip/transport_ws.go creates a wsutil.Reader without setting MaxFrameSize, allowing NextFrame to accept a client-controlled header.Length before ParseMaxMessageLength is applied. An unauthenticated WS or WSS peer can send a frame header declaring an extremely large payload, causing an oversized allocation or a makeslice length panic before the payload is read and crashing or exhausting memory in the server process. This issue is fixed in version 1.4.3.

    SIPGO is a library for writing SIP services in the GO language. Prior to 1.4.1, ParserStream.parseSingle in sip/parser_stream.go allocates a SIP body buffer from the client-controlled Content-Length header before ParseMaxMessageLength is enforced. An unauthenticated peer can send a stream-transport message over TCP, TLS, WS, or WSS with an oversized declared length, causing excessive memory allocation and denial of service before the body is read. This issue is fixed in version 1.4.1.

  • Dec 16, 2025SIPGO is a library for writing SIP services in the GO language.CVE-2025-68274 · Other software · emiago · reported by GitHubHigh 8.7

    SIPGO is a library for writing SIP services in the GO language. Starting in version 0.3.0 and prior to version 1.0.0-alpha-1, a nil pointer dereference vulnerability is in the SIPGO library's `NewResponseFromRequest` function that affects all normal SIP operations. The vulnerability allows remote attackers to crash any SIP application by sending a single malformed SIP request without a To header. The vulnerability occurs when SIP message parsing succeeds for a request missing the To header, but the response creation code assumes the To header exists without proper nil checks. This affects routine operations like call setup, authentication, and message handling - not just error cases. This vulnerability affects all SIP applications using the sipgo library, not just specific configurations or edge cases, as long as they make use of the `NewResponseFromRequest` function. Version 1.0.0-alpha-1 contains a patch for the issue.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
