The stream parser fails to validate declared Content-Length header sizes before initiating memory allocations, allowing remote, unauthenticated attackers to trigger process memory exhaustion and application crashes.\n\n## TL;DR\nUnauthenticated remote attackers can crash sipgo-based services by transmitting a crafted SIP stream with an excessively large Content-Length header, causing the Go application to exhaust memory and terminate.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-789\n- **Attack Vector**: Network (AV:N)\n- **CVSS Score**: 7.5 (High)\n- **Exploit Status**: Proof-of-Concept\n- **CISA KEV Status**: Not Listed\n- **Remediation Status**: Patched in v1.4.1\n\n## Affected Systems\n\n- Applications utilizing emiago/sipgo prior to version 1.4.1\n- SIP gatekeepers, routers, and endpoints listening on TCP/TLS/WS/WSS transports using sipgo\n- **sipgo**: < 1.4.1 (Fixed in: `1.4.1`)\n\n## Mitigation\n\n- Upgrade library dependencies to version 1.4.1 or higher.\n- Enforce explicit limit configurations via MaxMessageLength.\n- Filter excessively large Content-Length values at the network boundary.\n\n**Remediation Steps:**\n1. Open a terminal in the root directory of your Go application.\n2. Execute the update command: go get github.com/emiago/sipgo@v1.4.1\n3. Clean up unnecessary module paths by executing: go mod tidy\n4. Rebuild and deploy the updated service binary.\n\n## References\n\n- [GitHub Security Advisory GHSA-pg59-5vwg-4jxq](https://github.com/emiago/sipgo/security/advisories/GHSA-pg59-5vwg-4jxq)\n- [Fix Commit a7be60a0](https://github.com/emiago/sipgo/commit/a7be60a07f48c06b3cdd5a7d35eb820b3df5736c)\n- [sipgo v1.4.1 Release Notes](https://github.com/emiago/sipgo/releases/tag/v1.4.1)\n- [CVE-2026-58268 Record](https://www.cve.org/CVERecord?id=CVE-2026-58268)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-58268) - Automated Vulnerability Intelligence*", "creation_timestamp": "2026-09-22T20:31:35.872004Z"} 2026-09-22T20:31:35.872004+00:00
