Attackers can trigger anonymous workflows with forged headers so reviewer notifications point to attacker domains, capturing capability tokens to submit decisions executed with owner credentials.","state":0,"publishedAt":"2026-10-05T11:09:45.174+00:00","modifiedAt":"2026-10-05T14:13:10.868+00:00","affected":[{"ecosystem":"Vendor product","name":"heym","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"heymrun\",\n                    \"product\": \"heym\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"0.0.112\"\n                        },\n                        {\n                            \"version\": \"0.0.112\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":5.3,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/heymrun/heym/security/advisories/GHSA-6rv3-wh25-7pg5","https://www.vulncheck.com/advisories/heym-before-0.0.112-hitl-review-token-leak-via-spoofable-origin-header"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-105396","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-105396","identifiers":["CVE-2026-105396"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
