In versions 5.7.1 and earlier, the MCP SSE server allows unauthenticated cross-origin MCP tool invocation due to an empty default secret. This issue was partially addressed by CVE-2026-46701 in version 5.4.5 by closing the CORS flaw (with Access-Control-Allow-Origin now set only for localhost origins), but the empty-default-secret flaw described in the title remained: the SSE MCP server still defaulted to an empty secret, _isAuthorized() still returned true when the secret was empty, and a non-loopback bind only produced a warning. As a result, the server still ran fully unauthenticated by default. Any non-browser caller (for example, curl, SSRF, or a 0.0.0.0 bind) could invoke all 22 MCP tools (config_set, agent_spawn, blackboard_write, token_*) with no credentials. This issue was fixed in version 5.7.2."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"Jovancoding","product":"Network-AI","versions":[{"version":"< 5.7.2","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","baseScore":9.1,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":5.2}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-06-18T19:42:39.963767Z","id":"CVE-2026-48814","options":[{"exploitation":"poc"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-306"}]}],"references":[{"url":"https://github.com/Jovancoding/Network-AI/releases/tag/v5.7.2","source":"security-advisories@github.com"},{"url":"https://github.com/Jovancoding/Network-AI/security/advisories/GHSA-r78r-rwrf-rjwp","source":"security-advisories@github.com"},{"url":"https://github.com/advisories/GHSA-j3vx-cx2r-pvg8","source":"security-advisories@github.com"},{"url":"https://github.com/Jovancoding/Network-AI/security/advisories/GHSA-r78r-rwrf-rjwp","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}
