{"id":"CVE-2026-92701","summary":"Cocos AI: Intra-handshake attested TLS implementation is vulnerable to session-misbinding attacks for Intel TDX verifier path","details":"trusted execution environments. In versions up to and including 0.8.2, the intra-handshake attested TLS (aTLS) Intel TDX verification path does not copy the expected current-session freshness value into the TDX quote-body policy before quote validation, so structurally valid TDX QuoteV4 Evidence is accepted without checking that its REPORT_DATA field matches the reportData expected for the current session. A relying party using this path can therefore accept Evidence with a mismatched or reused reportData and release application data after the handshake, enabling session-misbinding to an unintended attestation context. The issue is fixed in version 0.9.0.","aliases":["GHSA-4px3-wj2x-xx47"],"modified":"2026-09-19T11:30:17.792567035Z","published":"2026-09-18T17:06:18.173Z","database_specific":{"cwe_ids":["CWE-346","CWE-354"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92701.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92701.json"},{"type":"WEB","url":"https://github.com/ultravioletrs/cocos/releases/tag/v0.9.0"},{"type":"ADVISORY","url":"https://github.com/ultravioletrs/cocos/security/advisories/GHSA-4px3-wj2x-xx47"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92701"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ultravioletrs/cocos","events":[{"introduced":"0"},{"fixed":"b44780df95a34cf0906c6af9d06e94f56e4811f2"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"0.9.0"}]}}],"versions":["v0.8.2","v0.8.1","v0.8.0","v0.7.0","v0.6.0","v0.5.2","v0.5.1","v0.5.0","v0.4.0","v0.3.1","v0.3.0","v0.2.0","v0.1.0","v0.0.2","v0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-92701.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
