{"id":"CVE-2026-30968","summary":"Coral Server has insufficient validation of agent identity for SSE connections","details":"Coral Server is open collaboration infrastructure that enables communication, coordination, trust and payments for The Internet of Agents. Prior to 1.1.0, the SSE endpoint (/sse/v1/...) in Coral Server did not strongly validate that a connecting agent was a legitimate participant in the session. This could theoretically allow unauthorized message injection or observation. This vulnerability is fixed in 1.1.0.","aliases":["GHSA-2rj5-3pgm-xqw9"],"modified":"2026-04-02T13:24:00.703929Z","published":"2026-03-10T17:24:11.604Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30968.json","cwe_ids":["CWE-862"],"cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/Coral-Protocol/coral-server/releases/tag/v1.1.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30968.json"},{"type":"ADVISORY","url":"https://github.com/Coral-Protocol/coral-server/security/advisories/GHSA-2rj5-3pgm-xqw9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-30968"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/Coral-Protocol/coral-server","events":[{"introduced":"0"},{"fixed":"0c41f383fd9127d440012301b284f47e90a6da82"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"1.1.0"}]}},{"type":"GIT","repo":"https://github.com/coral-protocol/coral-server","events":[{"introduced":"0"},{"fixed":"0c41f383fd9127d440012301b284f47e90a6da82"}]}],"versions":["stabletutorial","v0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-30968.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
